74AHC2G125 74AHCT2G125 Dual buffer/line driver 3-state Rev. 4 2 January 2019 Product data sheet 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. 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 3.
