74L VC02AQuad 2-input NOR gate
FEA TURES
•Wide supply range of 1.2V to 3.6V
•Complies with JEDEC standard no. 8-1A
•Inputs accept voltages up to 5.5V
•CMOS low power consumption
•Direct interface with TTL levels
DESCRIPTION
The 74LVC02A is a high performance, low-power, low-voltage,
Si-gate CMOS device and superior to most advanced CMOS
compatible TTL families.
Inputs can be driven from either 3.3 V or 5 V devices. This feature
allows the use of these devices as translators in a mixed 3.3 V/5 V
environment.
The 74LVC02A provides the 2-input NOR function.
•5-volt tolerant inputs, for interfacing with 5-volt logic
