DESCRIPTION

The 74LX1G04 is a low voltage CMOS SINGLE INVERTER 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 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
