CMOS IC
SINGLE 2-INPUT NOR GATE

DESCRIPTION
The U74LVC1G02 is a 2-input NOR gate device which provides
the Function Y=A+B in positive logic.
This device has power-down protective circuit preventing device
from destruction when it is powered down.

FEATURES
* Operation Voltage Range: 1.6V ~ 5.5V
* Low Power Current: ICC=10μA (Max.)
* ±24mA Output Drive (VCC=3.0V)
* Power Down Protection
