74AHC2G125; 74AHCT2G125
Dual buffer/line driver; 3-state
Rev. 02 — 22 December 2008
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
I Symmetrical output impedance
I High noise immunity
I Low power dissipation
I Balanced propagation delays
I Multiple package options
I 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
