74AHC2G126; 74AHCT2G126 Dual buffer/line driver; 3-state Rev. 04 — 27 April 2009 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 I I I I I I Symmetrical output impedance High noise immunity Low power dissipation Balanced propagation delays Multiple package options ESD protection: N HBM JESD22-A114E: exceeds 2000 V N MM JESD22-A115-A: exceeds 200 V N CDM JESD22-C101C: exceeds 1000 V I Specified from −40 °C to +125 °C 3.
