DESCRIPTION

The 74LX1G32 is a low voltage CMOS SINGLE 2-INPUT OR GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

It is ideal for 1.65 to 5.5 VCC operations and low power and low noise applications. The internal circuit is composed of 3 stages including buffer

SOT23-5 SC70-5

output, which provide high noise immunity and stable output.

Power down protection is provided on input and output and 0 to 7V can be accepted on inputs with no regard to the supply voltage. It can be interfaced to 5V signal environment for inputs in mixed 3.3/5V system.

All inputs and outputs are equipped with protection circuits against static discharge.
