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

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
