Bus buffer/line driver; 3-state
Rev. 1 — 26 March 2013
Product data sheet
1. General description
74AHC1G126-Q100 and 74AHCT1G126-Q100 are high-speed Si-gate CMOS devices.
They provide one non-inverting buffer/line driver with 3-state output. The output enable
input pin (OE) controls the 3-state output. A LOW at pin OE 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.
2. Features and benefits
