74AHCT2G125-Q100
Dual buffer/line driver; 3-state
Rev. 1 — 11 March 2014
Product data sheet
1. General description
The 74AHC2G125-Q100 and 74AHCT2G125-Q100 are high-speed Si-gate CMOS
devices. They provide a dual non-inverting buffer/line driver with 3-state output. The
output enable input (nOE) controls the 3-state output. A HIGH at nOE causes the output
to assume a high-impedance OFF-state.
The AHC device has CMOS input switching levels and supply voltage range 2 V to 5.5 V.
The AHCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
