Each gate performs the Boolean function Y = A + B in positive logic. 8.2 Functional Block Diagram xA xY xB 8.3 Feature Description 8.3.1 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, then 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; a 10-kΩ resistor, however, is recommended and will typically meet all requirements. 8.3.2 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. 8.3.3 Clamp Diode Structure The outputs to this device have both positive and negative clamping diodes, and the inputs to this device have negative clamping diodes only as shown in Figure 8-1. 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, three 2-input OR gates are combined to produce a 4-input OR gate function as shown in Figure 9-1. The fourth gate can be used for another application in the system, or the inputs can be grounded and the channel left unused. The SNx4AHC32 is used to directly control the Enable pin of a fan driver. The fan driver requires only one input signal to be HIGH before being enabled, and should be disabled in the event that all signals go LOW. The 4-input OR gate function combines the four individual overheat signals into a single active-high enable signal. Temperature sensors can often be spread throughout a system rather than being in a centralized location. This would mean longer length traces or wires to pass signals through leading to slower edge transitions. This makes the SNx4AHC32 useful for combining the incoming signals. 9.2 Typical Application Device 1 Overheat Device 2 Overheat Fan Driver EN Device 3 Overheat Device 4 Overheat Figure 9-1. Typical Application Block 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 electrical characteristics of the device as described in the Electrical Characteristics section. The positive voltage supply must be capable of sourcing current equal to the maximum static supply current, ICC, listed in the Electrical Characteristics, and any transient current required for switching. Submit Document Feedback Copyright © 2023 Texas Instruments Incorporated Product Folder Links: SN74AHC32 SN54AHC32 11 SN74AHC32, SN54AHC32 www.ti.com SCLS247K – OCTOBER 1995 – REVISED OCTOBER 2023 The ground must be capable of sinking current equal to the total current to be sunk by all outputs of the SNx4AHC32 plus the maximum supply current, ICC, listed in the Electrical Characteristics, and any transient current required for switching. The logic device can only sink as much current that can be sunk into its ground connection. Be sure to not exceed the maximum total current through GND listed in the Absolute Maximum Ratings. The SNx4AHC32 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. The SNx4AHC32 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 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 application note. Thermal increase can be calculated using the information provided in Thermal Characteristics of Standard Linear and Logic (SLL) Packages and Devices application note. 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 to be considered a logic LOW, and 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. The unused inputs 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 will 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 drive current of the controller, leakage current into the SNx4AHC32 (as specified in the Electrical Characteristics), and the desired input transition rate limits the resistor size. A 10-kΩ resistor value is often used due to these factors. Refer to the Feature Description section for additional information regarding the inputs for this device. 9.2.1.3 Output Considerations 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. Unused outputs can be left floating. Do not connect outputs directly to VCC or ground. Refer to the Feature Description section for additional information regarding the outputs for this device. 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; by design, however, it will optimize performance. This can be accomplished by providing short, appropriately sized traces from the SNx4AHC32 to one or more of the receiving devices. 3. Ensure the resistive load at the output is larger than (VCC / IO(max)) Ω. Doing this will prevent the maximum output current from the Absolute Maximum Ratings from being violated. Most CMOS inputs have a resistive load measured in MΩ; much larger than the minimum calculated previously. 12 Submit Document Feedback Copyright © 2023 Texas Instruments Incorporated Product Folder Links: SN74AHC32 SN54AHC32 SN74AHC32, SN54AHC32 www.ti.com SCLS247K – OCTOBER 1995 – REVISED OCTOBER 2023 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 Curves Device 1 Device 2 Device 3 Device 4 EN Figure 9-2. Application Timing Diagram 9.3 Power Supply Recommendations The power supply can be any voltage between the minimum and maximum supply voltage rating located in the Recommended Operating Conditions. 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 capacitors 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 the following layout example. 9.4 Layout 9.4.1 Layout Guidelines When using multiple-input and multiple-channel logic devices, inputs must never 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.
