Hex inverting Schmitt trigger
Rev. 7 — 9 December 2015
Product data sheet
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.
