8 Detailed Description
8.1 Overview
This device contains six independent inverters with open-drain outputs. Each gate performs the Boolean function
Y = A in positive logic.
8.2 Functional Block Diagram
xA
xY
8.3 Feature Description
8.3.1 CMOS Open-Drain Outputs
The open-drain output allows the device to sink current to GND but not to source current from VCC. When the
output is not actively pulling the line low, it will go into a high impedance state. This allows the device to be used
for a wide variety of applications, including up-translation and down-translation, as the output voltage can be
determined by an external pull-up resistor.
The current drive capability of this device creates 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 power output of the device
to be limited to avoid thermal runaway and damage due to over-current. The electrical and thermal limits defined
the in the Absolute Maximum Ratingsmust be followed at all times.
The SN74HC05 can drive a load with a total capacitance less than or equal to the maximum load listed in
the Switching Characteristics - 74 connected to a high-impedance CMOS input while still meeting all of the
datasheet specifications. Larger capacitive loads can be applied, however it is not recommended to exceed the
provided load value. If larger capacitive loads are required, it is recommended to add a series resistor between
the output and the capacitor to limit output current to the values given in the Absolute Maximum Ratings.
8.3.2 Standard CMOS Inputs
Standard CMOS inputs are high impedance and are typically modeled as a resistor from the input to ground
in parallel with the input capacitance given in the Electrical Characteristics - 74. 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 - 74, using ohm's law (R = V ÷ I).
Signals applied to the inputs need to have fast edge rates, as defined by the input transition time in the
Recommended Operating Conditions to avoid excessive current consumption and oscillations. If a slow or noisy
input signal is required, a device with a Schmitt-trigger input should be used to condition the input signal prior to
the standard CMOS input.

9 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. 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, one open-drain inverter is used as shown in Figure 9-1. The other five channels can be used
for other applications in the system, or the inputs can be grounded and the channels left unused.
This device is used to directly control an LED. The LED is on when the input is high, and off when the input is
low.
9.2 Typical Application

Input
Figure 9-1. Typical application schematic
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 - 74.
The ground must be capable of sinking current equal to the total current to be sunk by all outputs of the
SN74HC05 plus the maximum supply current, ICC, listed in Electrical Characteristics - 74. The logic device can
only sink as much current as is provided by the external pull-up resistor or other supply source. Be sure not to
exceed the maximum total current through GND listed in the Absolute Maximum Ratings.
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
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 SN74HC05, as specified in the Electrical Characteristics - 74, and the desired input transition rate. A 10-kΩ
resistor value is often used due to these factors.
The SN74HC05 has standard CMOS inputs, so input signal edge rates cannot be slow. Slow input edge
rates can cause oscillations and damaging shoot-through current. The recommended rates are defined in the
Recommended Operating Conditions.
Refer to Section 8.3 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 - 74. The plot in provides a
typical relationship between output voltage and current for this device.
Open-drain outputs can be directly connected together to produce a wired-AND. This is possible because the
outputs cannot source current, and thus can never be in bus-contention.
Unused outputs can be left floating. Do not connect outputs directly to VCC or ground.
Refer to Section 8.3 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 Section 11.
2. Ensure the capacitive load at the output is ≤ 70 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 SN74HC05
to the receiving device.
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 megaohms; much larger than the minimum calculated above.
4. Thermal issues are rarely a concern for logic gates, however the power consumption and thermal increase
can be calculated using the steps provided in the application report, CMOS Power Consumption and Cpd

10 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 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
Figure 11-1.
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. 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.
