74HC2G34-Q100; 74HCT2G34-Q100
Dual buffer gate
Rev. 2 — 4 November 2013
Product data sheet
1. General description
The 74HC2G34-Q100; 74HCT2G34-Q100 is a dual buffer. 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.
