74LVC14A Hex inverting Schmitt trigger with 5 V tolerant input Rev. 04 -- 15 February 2005 Product data sheet 1. General description The 74LVC14A is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device as a translator in a mixed 3.3 V and 5 V environment. The 74LVC14A provides six inverting buffers with Schmitt-trigger action. It is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. 2. Features Wide supply voltage range from 1.2 V to 3.6 V 5 V tolerant input for interfacing with 5 V logic CMOS low-power consumption Direct interface with TTL levels Inputs accept voltages up to 5.5 V Unlimited input rise and fall times Complies with JEDEC standard: JESD8-B/JESD36 (2.7 V to 3.6 V) ESD protection: HBM EIA/JESD22-A114-B exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V Multiple package options Specified from -40 C to +85 C and from -40 C to +125 C 3.
