SDLS049C – DECEMBER 1983 – REVISED NOVEMBER 2016
SNx414 and SNx4LS14 Hex Schmitt-Trigger Inverters
1 Features
3 Description
•
•
•
Each circuit in SNx414 and SNx4LS14 functions as
an inverter. However, because of the Schmitt-Trigger
action, they have different input threshold levels for
positive-going (VT+) and negative-going (VT–) signals.
1
Operation From Very Slow Edges
Improved Line-Receiving Characteristics
High Noise Immunity
2 Applications
•
•
•
•
•
•
HVAC Gateways
Residential Ductless Air Conditioning Outdoor
Units
Robotic Controls
Industrial Stepper Motors
Power Meter and Power Analyzers
Digital Input Modules for Factory Automation
These circuits are temperature compensated and can
be triggered from the slowest of input ramps and still
give clean, jitter-free output signals.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

8 Detailed Description
8.1 Overview
The SNx414 and SNx4LS14 Schmitt-Trigger devices contain six independent inverters. They perform the
Boolean function Y = A in positive logic.
Schmitt-Trigger inputs are designed to provide a minimum separation between positive and negative switching
thresholds. This allows for noisy or slow inputs that would cause problems such as oscillation or excessive
current draw with normal CMOS inputs.

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
The SNx414 and SNx4LS14 device is a Schmitt-Trigger input CMOS device that can be used for a multitude of
inverting buffer type functions. The application shown here takes advantage of the Schmitt-Trigger inputs to
produce a delay for a logic input.
9.2 Typical Application
Copyright © 2016, Texas Instruments Incorporated
Figure 28. Simplified Application Schematic
9.2.1 Design Requirements
This device uses CMOS technology. Take care to avoid bus contention because it can drive currents that would
exceed maximum limits. Parallel output drive can create fast edges into light loads, so consider routing and load
conditions to prevent ringing.
9.2.2 Detailed Design Procedure
This circuit is designed around an RC network that produces a slow input to the second inverter. The RC time
constant (τ) is calculated from: τ = RC.
The delay time for this circuit is from tdelay(min) = –ln |1 – VT+(min) / VCC| τ to tdelay(max) = –ln |1 – VT+(max) / VCC| τ. It
must be noted that the delay is consistent for each device, but because the switching threshold is only ensured
between the minimum and maximum value, the output pulse length varies between devices. These values must
be calculated by using the minimum and maximum ensured VT+ values in the Electrical Characteristics.
The resistor value must be chosen such that the maximum current to and from the SNx414/SNx4LS14 is 8 mA at
5-V VCC.

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. The VCC terminal must have a good bypass capacitor to prevent power
disturbance. TI recommends using a 0.1-µF capacitor on the VCC terminal, and must be placed as close as
possible to the pin for best results.
11 Layout
11.1 Layout Guidelines
When using multiple bit logic devices, inputs must never float. 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
three of the four buffer gates are used. Such inputs 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 high or low bias 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 they are tied to GND or
VCC, whichever makes more sense or is more convenient. Floating outputs are generally acceptable, unless the
part is a transceiver.
