U74AHC2G125
CMOS IC
DUAL BUFFER/LINE DRIVER;
3-STATE

DESCRIPTION
The U74AHC2G125 is a high speed, Si-gate CMOS device.
The U74AHC2G125 provides a dual non-inverting buffer/line
drivers 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.

TSSOP-8
FEATURES
* Symmetrical output impedance
* High noise immunity
* Low power dissipation
* Balanced propagation delays
* Multiple package options
* Specified from -40 °C to +125 °C
