74AHC2G126; 74AHCT2G126
Dual buffer/line driver; 3-state
Rev. 8 — 19 November 2018
Product data sheet
1. General description
The 74AHC2G126 and 74AHCT2G126 are high-speed Si-gate CMOS devices. They provide a
dual non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by the
output enable input (nOE). A LOW 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.

Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
