1. general description the 74ahcv14a is a hex inverter with schmitt-trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. inputs are overvoltage tolerant. this feature a llows the use of these devices as translators in mixed voltage environments. this device is fully specified for pa rtial power down applications using i off . the i off circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down. 2. features and benefits ? wide supply voltage range from 1.8 v to 5.5 v ? typical t pd of 3.2 ns at 5 v ? typical v ol(p) < 0.8 v at v cc = 3.3 v, t amb = 25 ? c ? typical v oh(v) > 2.3 v at v cc = 3.3 v, t amb = 25 ? c ? supports mixed-mode voltage operation on all ports ? i off circuitry provides partial power-down mode operation ? latch-up performance exceeds 250 ma per jesd 78 class ii ? esd protection: ? hbm ansi/esda/jedec js-001 class 2 exceeds 3 kv ? mm jesd22-a115-a exceeds 200 v ? cdm jesd22-c101e exceeds 2 kv ? specified from ? 40 ? c to +85 ? c and from ? 40 ? c to +125 ? c 74ahcv14a hex inverting schmitt trigger rev. 3 17 november 2016 product data sheet downloaded from: http:///
