3 Description

The SN54LVC14A hex Schmitt-trigger inverter is

designed for 2.7-V to 3.6-V VCC operation, and the

SN74LVC14A hex Schmitt-trigger inverter is designed

for 1.65-V to 3.6-V VCC operation.

The devices contain six independent inverters and

perform the Boolean function Y = A.

Inputs can be driven from either 3.3-V or 5-V

devices. This feature allows the use of these devices

as translators in a mixed 3.3-V or 5-V system

environment.
