74LV14DB,112

74LV14 Hex inverting Schmitt trigger Rev. 9 14 September 2021 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 hysteresis voltage V . T+ T- H 2. Features and benefits Wide supply voltage range from 1.0 V to 5.5 V CMOS low power dissipation 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 T = 25 C OH CC amb Latch-up performance exceeds 100 mA per JESD 78 Class II Level B Complies with JEDEC standards: JESD8-7 (1.65 V to 1.95 V) JESD8-5 (2.3 V to 2.7 V) JESD8C (2.7 V to 3.6 V) JESD36 (4.5 V to 5.5 V) ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from -40 C to +85 C and from -40 C to +125 C 3.
