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

 Symmetrical output impedance

 High noise immunity

 Low power dissipation

 Balanced propagation delays

 Multiple package options

 ESD protection:

 HBM JESD22-A114E: exceeds 2000 V

 MM JESD22-A115-A: exceeds 200 V

 CDM JESD22-C101C: exceeds 1000 V

 Specified from 40 C to +125 C
