74LV14 Hex inverting Schmitt trigger Rev. 6 12 December 2011 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 V and the negative voltage V is defined as the input T+ T hysteresis voltage V . H 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 = 2.7 V and V = 3.6 V CC CC Typical output ground bounce < 0.8 V at V = 3.3 V and T = 25 C CC amb Typical HIGH-level output voltage (V ) undershoot: > 2 V at V = 3.3 V and OH CC T = 25 C amb ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from 40 Cto+85 C and from 40 Cto+125 C 3.
