Dual buffer/line driver; 3-state
Rev. 2 — 1 November 2018
Product data sheet
1. General description
The 74HC2G125-Q100; 74HC2G125-Q100 are dual buffer/line drivers with 3-state outputs
controlled by the output enable inputs (nOE). Inputs include clamp diodes which enable 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.
