![]() 74LVC2G02
DUAL 2-INPUT NOR GATE
Description
Pin Assignments
The 74LVC2G02 is a dual, two input NOR gate. Both gates have
push-pull outputs designed for operation over a power supply range
of 1.65V to 5.5V. The device is fully specified for partial power down
applications using IOFF. The IOFF circuitry disables the output,
preventing damaging current backflow when the device is powered
down. Each gate performs the positive Boolean function:
Y A B or Y A B

GND 4
5 2A
Features
Wide Supply Voltage Range from 1.65 to 5.5V
± 24mA Output Drive at 3.3V
CMOS Low Power Consumption
IOFF Supports Partial-Power-Down Mode Operation
Inputs accept up to 5.5V
Schmitt Trigger Action at all inputs makes the circuit tolerant
for slower input rise and fall times. The hysteresis is typically
100mV at VCC = 3.0V.
ESD Protection Exceeds JESD 22
2000-V Human Body Model (A114)
Exceeds 1000-V Charged Device Model (C101)
Latch-Up Exceeds 100mA per JESD 78, Class I
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
