1. General description
The 74AHC2G125 and 74AHCT2G125 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 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.
