74HC3G34-Q100; 74HCT3G34-Q100
Dual non-inverting Schmitt trigger
Rev. 1 — 16 May 2013
Product data sheet
1. General description
The 74HC3G34-Q100; 74HCT3G34-Q100 are triple buffers. Inputs include clamp diodes.
This enables the use of current limiting resistors to interface inputs to voltages in excess
of V
CC
.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
