8.1 Overview
This device contains six independent inverters with Schmitt-trigger inputs. 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 Balanced CMOS Push-Pull Outputs
A balanced output allows the device to 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
over-current. The electrical and thermal limits defined in the Absolute Maximum Ratings must be followed at all
times.
The SN74HC14 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 CMOS Schmitt-Trigger 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).
The Schmitt-trigger input architecture provides hysteresis as defined by ΔVT in the Electrical Cahracteristics 74, which makes this device extremely tolerant to slow or noisy inputs. While the inputs can be driven much
slower than standard CMOS inputs, it is still recommended to properly terminate unused inputs. Driving the
inputs slowly will also increase dynamic current consumption of the device. For additional information regarding
Schmitt-trigger inputs, please see Understanding Schmitt Triggers.

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. Customers should validate and test their design
implementation to confirm system functionality.
9.1 Application Information
This device can be used to add an additional stage to a counter with an external flip-flop. Because counters
use a negative edge trigger, the flip-flop's clock input must be inverted to provide this function. This function
only requires one of the six available inverters in the device, so the remaining channels can be used for other
applications needing an inverted signal or improved signal integrity. Unused inputs must be terminated at VCC or
GND. Unused outputs can be left floating.

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 supply must be capable of sourcing current equal to the total current to be sourced by all outputs of the
SN74HC14 plus the maximum supply current, ICC, listed in the Electrical Characteristics - 74. The logic device
can only source or sink as much current as it is provided at the supply and ground pins, respectively. Be sure not
to exceed the maximum total current through GND or VCC 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
Input signals must cross Vt-(min) to be considered a logic LOW, and Vt+(max) 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 SN74HC14, 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 SN74HC14 has no input signal transition rate requirements because it has Schmitt-trigger inputs.
Another benefit to having Schmitt-trigger inputs is the ability to reject noise. Noise with a large enough amplitude
can still cause issues. To know how much noise is too much, please refer to the ΔVT(min) in the Electrical
Characteristics - 74. This hysteresis value will provide the peak-to-peak limit.
Unlike what happens with standard CMOS inputs, Schmitt-trigger inputs can be held at any valid value without
causing huge increases in power consumption. The typical additional current caused by holding an input at a
value other than VCC or ground is plotted in the Typical Characteristics.
Refer to the Feature Description 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 - 74. Similarly,
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.
Unused outputs can be left floating. Do not connect outputs directly to VCC or ground.
Refer to Feature Description 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.
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 SN74HC14
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.
