DESCRIPTIONThe 74LX1G32isa low voltage CMOS SINGLE
2-INPUT OR GATE fabricated with sub-micron
silicon gate and double-layer metal wiringC2 MOS
tecnology.is idealfor 1.65to5.5VCC operations and low
power and low noise applications. The internal
circuitis composedof3 stages including buffer
output, which provide high noise immunity and
stable output.
Power downprotectionis providedoninput and
output and0to7V canbe acceptedon inputs with regardto the supply voltage.It can be
interfacedto5V signal environmentfor inputsin
mixed 3.3/5V system.
All inputs and outputs are equipped with
protection circuits against static discharge.
