74L VC14A
DESCRIPTION
The 74LVC14A is a high-performance, low power, low-voltage
Si-gate CMOS device and superior to most advanced CMOS
compatible TTL families.
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/5 V
environment.
The 74LVC14A provides six inverting buffers with Schmitt-trigger
action. It is capable of transforming slowly changing input signals
into sharply defined, jitter-free output signals.
VCC = 3.3 V
