CMOS IC
DUAL BUFFER/LINE DRIVER;
3-STATE
DESCRIPTION
The U74HC2G125 is a high speed, Si-gate CMOS device.
The U74HC2G125 provides two non-inverting buffer/line
drivers with 3-state output. The 3-state output is controlled by the
output enable input (pin nOE ). A HIGH level at pin nOE causes
the output to assume a high-impedance OFF-state.
TSSOP-8
FEATURES
* Wide supply voltage range from 2.0V to 6.0V
* Symmetrical output impedance
* High noise immunity
* Low power consumption
* Balanced propagation delays
* Multiple package options
* Specified from -40 °C to +125 °C
