74LV14
Hex inverting Schmitt trigger
Rev. 6 — 12 December 2011 Product data sheet
1. General description
The 74L V14 is a low-voltage Si-gate CM OS device that is pin and function comp atible 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 point s for positive and negative-going signals. The dif ference
between the positive voltage V

2. Features and benefits
Wide operating voltage: 1.0 V to 5.5 V
Optimized for low voltage applications: 1.0 V to 3.6 V
Accepts TTL input levels between V
Typical output ground bounce < 0.8 V at V
Typical HIGH-level output voltage (V
