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.
2. Features and benefits
