Datasheet

1. General description
The 74LVC14A provides six inverting buffers with Schmitt trigger input. It is capable of
transforming slowly-changing input signals into sharply defined, jitter-free output signals.
The inputs switch at different points for positive and negative-going signals. The difference
between the positive voltage V
T+
and the negative voltage V
T
is defined as the input
hysteresis voltage V
H
.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this
device as a translator in mixed 3.3 V and 5 V applications.
2. Features and benefits
 Wide supply voltage range from 1.2 V to 3.6 V
