Each gate performs the Boolean function Y = A ● B in positive logic. 8.2 Functional Block Diagram xA xY xB 8.3 Balanced CMOS Push-Pull Outputs This device includes balanced CMOS push-pull outputs. The term balanced indicates that the device can sink and source similar currents. The drive capability of this device may create fast edges into light loads so routing and load conditions should be considered to prevent ringing. Additionally, the outputs of this device are capable of driving larger currents than the device can sustain without being damaged. It is important for the output power of the device to be limited to avoid damage due to overcurrent. The electrical and thermal limits defined in the Absolute Maximum Ratings must be followed at all times. Unused push-pull CMOS outputs should be left disconnected. 8.4 Standard CMOS Inputs This device includes standard CMOS inputs. Standard CMOS inputs are high impedance and are typically modeled as a resistor in parallel with the input capacitance given in the Electrical Characteristics. The worst case resistance is calculated with the maximum input voltage, given in the Absolute Maximum Ratings, and the maximum input leakage current, given in the Electrical Characteristics, using Ohm's law (R = V ÷ I). Standard CMOS inputs require that input signals transition between valid logic states quickly, as defined by the input transition time or rate in the Recommended Operating Conditions table. Failing to meet this specification will result in excessive power consumption and could cause oscillations. More details can be found in Implications of Slow or Floating CMOS Inputs. Do not leave standard CMOS inputs floating at any time during operation. Unused inputs must be terminated at VCC or GND. If a system will not be actively driving an input at all times, a pull-up or pull-down resistor can be added to provide a valid input voltage during these times. The resistor value will depend on multiple factors, however a 10-kΩ resistor is recommended and will typically meet all requirements. 8.5 Clamp Diode Structure The inputs and outputs to this device have both positive and negative clamping diodes as depicted in Electrical Placement of Clamping Diodes for Each Input and Output. CAUTION Voltages beyond the values specified in the Absolute Maximum Ratings table can cause damage to the device. The input and output voltage ratings may be exceeded if the input and output clampcurrent ratings are observed.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. 9.1 Application Information In this application, the SN74HC00 is used to create an active-low SR latch. The two additional gates can be used for a second active-low SR latch, individually used for their logic function, or the inputs can be grounded and both channels left unused. This device is used to drive the tamper indicator LED and provide one bit of data to the system controller. When the tamper switch outputs LOW, the output Q becomes HIGH. This output remains HIGH until the system controller addresses the event and sends a LOW signal to the R input which returns the Q output back to LOW. 9.2 Typical Application System Controller R1 R Tamper Switch Q S R2 Tamper Indicato r Figure 9-1. Typical Application Diagram 9.2.1 Design Requirements 9.2.1.1 Power Considerations Ensure the desired supply voltage is within the range specified in the Recommended Operating Conditions. The supply voltage sets the device's electrical characteristics as described in the Electrical Characteristics. The positive voltage supply must be capable of sourcing current equal to the total current to be sourced by all outputs of the SN74HC00 plus the maximum static supply current, ICC, listed in Electrical Characteristics and any transient current required for switching. The logic device can only source as much current as is provided by the positive supply source. Be sure not to exceed the maximum total current through VCC listed in the Absolute Maximum Ratings. The ground must be capable of sinking current equal to the total current to be sunk by all outputs of the SN74HC00 plus the maximum supply current, ICC, listed in Electrical Characteristics, and any transient current required for switching. The logic device can only sink as much current as can be sunk into its ground connection. Be sure not to exceed the maximum total current through GND listed in the Absolute Maximum Ratings. The SN74HC00 can drive a load with a total capacitance less than or equal to 50 pF while still meeting all of the data sheet specifications. Larger capacitive loads can be applied; however, it is not recommended to exceed 50 pF. Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: SN74HC00 SN54HC00 11 SN74HC00, SN54HC00 www.ti.com SCLS181H – DECEMBER 1982 – REVISED AUGUST 2021 The SN74HC00 can drive a load with total resistance described by RL ≥ VO / IO, with the output voltage and current defined in the Electrical Characteristics table with VOH and VOL. When outputting in the high state, the output voltage in the equation is defined as the difference between the measured output voltage and the supply voltage at the VCC pin. Total power consumption can be calculated using the information provided in CMOS Power Consumption and Cpd Calculation. Thermal increase can be calculated using the information provided in Thermal Characteristics of Standard Linear and Logic (SLL) Packages and Devices. CAUTION The maximum junction temperature, TJ(max) listed in the Absolute Maximum Ratings, is an additional limitation to prevent damage to the device. Do not violate any values listed in the Absolute Maximum Ratings. These limits are provided to prevent damage to the device. 9.2.1.2 Input Considerations Input signals must cross VIL(max) to be considered a logic LOW, and VIH(min) to be considered a logic HIGH. Do not exceed the maximum input voltage range found in the Absolute Maximum Ratings. Unused inputs must be terminated to either VCC or ground. These can be directly terminated if the input is completely unused, or they can be connected with a pull-up or pull-down resistor if the input is to be used sometimes, but not always. A pull-up resistor is used for a default state of HIGH, and a pull-down resistor is used for a default state of LOW. The resistor size is limited by drive current of the controller, leakage current into the SN74HC00, as specified in the Electrical Characteristics, and the desired input transition rate. A 10-kΩ resistor value is often used due to these factors. The SN74HC00 has CMOS inputs and thus requires fast input transitions to operate correctly, as defined in the Recommended Operating Conditions table. Slow input transitions can cause oscillations, additional power consumption, and reduction in device reliability. Refer to the Feature Description section for additional information regarding the inputs for this device. 9.2.1.3 Output Considerations The positive supply voltage is used to produce the output HIGH voltage. Drawing current from the output will decrease the output voltage as specified by the VOH specification in the Electrical Characteristics. The ground voltage is used to produce the output LOW voltage. Sinking current into the output will increase the output voltage as specified by the VOL specification in the Electrical Characteristics. Push-pull outputs that could be in opposite states, even for a very short time period, should never be connected directly together. This can cause excessive current and damage to the device. Two channels within the same device with the same input signals can be connected in parallel for additional output drive strength. Unused outputs can be left floating. Do not connect outputs directly to VCC or ground. Refer to Feature Description section for additional information regarding the outputs for this device. 12 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: SN74HC00 SN54HC00 SN74HC00, SN54HC00 www.ti.com SCLS181H – DECEMBER 1982 – REVISED AUGUST 2021 9.2.2 Detailed Design Procedure 1. Add a decoupling capacitor from VCC to GND. The capacitor needs to be placed physically close to the device and electrically close to both the VCC and GND pins. An example layout is shown in the Layout section. 2. Ensure the capacitive load at the output is ≤ 50 pF. This is not a hard limit, however it will ensure optimal performance. This can be accomplished by providing short, appropriately sized traces from the SN74HC00 to one or more of the receiving devices. 3. Ensure the resistive load at the output is larger than (VCC / IO(max)) Ω. This will ensure that the maximum output current from the Absolute Maximum Ratings is not violated. Most CMOS inputs have a resistive load measured in MΩ; much larger than the minimum calculated above. 4. Thermal issues are rarely a concern for logic gates; the power consumption and thermal increase, however, can be calculated using the steps provided in the application report, CMOS Power Consumption and Cpd Calculation. 9.2.3 Application Curve R S Q Figure 9-2.

Each VCC terminal should have a good bypass capacitor to prevent power disturbance. A 0.1-μF capacitor is recommended for this device. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power terminal as possible for best results, as shown in given example layout image. 11 Layout 11.1 Layout Guidelines When using multiple-input and multiple-channel logic devices inputs must not ever be left floating. In many cases, functions or parts of functions of digital logic devices are unused; for example, when only two inputs of a triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such unused input pins must not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. All unused inputs of digital logic devices must be connected to a logic high or logic low voltage, as defined by the input voltage specifications, to prevent them from floating. The logic level that must be applied to any particular unused input depends on the function of the device. Generally, the inputs are tied to GND or VCC, whichever makes more sense for the logic function or is more convenient. 11.2 Layout Example VCC Recommend GND flood fill for improved signal isolation, noise reduction, and thermal dissipation 1OE 1 VCC GND 0.1 F Bypass capacitor placed close to the device 1A1 2 20 19 2Y4 3 18 1Y1 Unused input tied to GND 1A2 4 17 2A4 2Y3 5 16 1Y2 Unused output 1A3 6 15 2A3 1Y3 Avoid 90° corners for signal lines GND 2OE left floating 2Y2 7 14 1A4 8 13 2A2 2Y1 9 10 12 11 1Y4 GND 2A1 Figure 11-1.
