General Description
The NC7NZ14 is a triple Inverter with Schmitt Trigger input
from Fairchild’s Ultra High Speed Series of TinyLogic
The device is fabricate d with advanced CMOS technology
to achieve ultra high speed with high output drive while
maintaining low static power dissipation over a very broad
V
operating range. Th e device is specified to operate
CC
over the 1.65V to 5.5V V
high impedance when V
up to 7V independent of V
