74AHCT2G125-Q100
Dual buffer/line driver; 3-state
Rev. 2 — 2 January 2019
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.
