DESCRIPTIONThe 74VHCT02Ais an advanced high-speed
CMOS QUAD 2-INPUT NOR GATE fabricated
with sub-micron silicon gate and double-layer
metal wiringC2 MOStechnology.
The internal circuitis composedof3 stages
including buffer output, which provide high noise
immunity and stable output.
Power down protectionis provided on all inputs
and outputs and0to 7V can be accepted on
inputs with no regardto the supply voltage. This
device canbe usedto interface5Vto 3V.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
