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 VT+ and the negative voltage VT- is defined as the input hysteresis voltage VH.

2. Features and benefits
