1. General description
The 74LV14 is a low-voltage Si-gate CMOS device that is pin and function compatible with
74HC14 and 74HCT14.
The 74LV14 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
.
2. Features and benefits
