1. general description the 74lvc3g14 provides three inverting buffers with schmitt trigger action. the inputs can be driven from either 3.3 v or 5 v devices. this feature allows the use of this device in a mixed 3.3 v and 5 v environment. schmitt trigger action at the inputs makes the circuit tolerant of slower input rise and fall time. this device is fully speci?ed for partial power-down applications using i off . the i off circuitry disables the output, preventing the damaging back?ow current through the device when it is powered down. 2. features n wide supply voltage range from 1.65 v to 5.5 v n 5 v tolerant input/output for interfacing with 5 v logic n high noise immunity n esd protection: u hbm jesd22-a114e exceeds 2000 v u mm jesd22-a115-a exceeds 200 v n 24 ma output drive (v cc = 3.0 v) n cmos low power consumption n latch-up performance exceeds 250 ma n direct interface with ttl levels n unlimited rise and fall times n multiple package options n speci?ed from - 40 c to +85 c and - 40 c to +125 c. 3. applications n wave and pulse shaper for highly noisy environment n astable multivibrator n monostable multivibrator. 74lvc3g14 triple inverting schmitt trigger with 5 v tolerant input rev. 07 12 june 2008 product data sheet
