74AHC1G125; 74AHCT1G125
Bus buffer/line driver; 3-state
Rev. 10 — 23 August 2012
Product data sheet
1. General description
74AHC1G125 and 74AHCT1G125 are high-speed Si-gate CMOS devices. They provide
one non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by
the output enable input (OE). A HIGH at OE 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-A114F: exceeds 2000 V
MM JESD22-A115-A: exceeds 200 V
CDM JESD22-C101E: exceeds 1000 V
