Product specification
Hex inverting Schmitt-trigger with 5V
tolerant input
74LVC14A
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
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.
•
Wave and pulse shapers for highly noisy environments
•
Astable multivibrators
•
Monostable multivibrators
