DESCRIPTION

The 74LX1G02 is a low voltage C MOS SINGLE
2-INPUT NOR GATE fabricated with sub-micron
silicon gate and double - layer metal wiring C

2

MOS
technology.
The internal circuit is composed of 3 stages
including buffer output, which provide high no ise
immunity and stable output.

PIN CONNECTION AND IEC LOGIC SYMBOLS

Power down protection is provided on all inputs
and 0 to 7V can be accepted on inp uts with no
regard to the supply voltage. This device can be
usedto interface5V to 3V.
All inputs and outputs are equipped with
protection circuits against static discharge.
