DESCRIPTIONThe 74LX1G02isa low voltage CMOS SINGLE
2-INPUT NOR GATE fabricated with sub-micron
silicon gate and double-layer metal wiringC2 MOS
technology.
The internal circuitis composedof3 stages
including buffer output, which provide high noise
immunity and stable output.
Power down protectionis providedonall inputs
and0to7V canbe acceptedon inputs withno
regardtothe supply voltage. This device canbe
usedto interface5Vto3V.
All inputs and outputs are equipped with
protection circuits against static discharge.
