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.
