Product specification
74LVC14A
Hex inverting Schmitt-trigger with 5V
tolerant input
2
1998 Apr 28
853-1907 19308
FEATURES
Wide supply voltage range of: 1.2 V to 3.6 V
In accordance with JEDEC standard no. 8-1A
Inputs accept voltages up to 5.5 V
CMOS low power consumption
Direct interface with TTL levels
APPLICATIONS
Wave and pulse shapers for highly noisy environments
Astable multivibrators
Monostable multivibrators
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.
