DESCRIPTION
74LVC02A
The 74LVC02A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 or 5 V devices. This
feature allows the use of these devices as translators in
a mixed 3.3 and 5 V environment.
The 74LVC02A provides the 2-input NOR function.
