74LVC14A Hex inverting Schmitt trigger with 5 V tolerant input Rev. 5 -- 23 December 2011 Product data sheet 1. General description The 74LVC14A 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 VT+ and the negative voltage VT is defined as the input hysteresis voltage VH. 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 mixed 3.3 V and 5 V applications. 2. Features and benefits 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 Unlimited input rise and fall times Inputs accept voltages up to 5.5 V Complies with JEDEC standard JESD8-C/JESD36 (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-B exceeds 200 V CDM JESD22-C101E exceeds 1000 V Multiple package options Specified from 40 C to +85 C and from 40 C to +125 C 3. Applications Wave and pulse shapers for highly noisy environments Astable multivibrators Monostable multivibrators 74LVC14A NXP Semiconductors Hex inverting Schmitt trigger with 5 V tolerant input 4.
