UHS Dual Inverter with
Schmitt Trigger Inputs
General Description
The NC7WZ14 is a dual inver ter with Schmi tt trigger inp ut
from Fairchild’s Ultra High Speed Series of TinyLogic
the space saving SC70 6-lead packag e. The dev ice is fabricated with advanced CM OS technology to achieve ultra
high speed with high output drive while maintaining low
static power dissipati on over a very broad V
range. The device is s pecified to operate over the 1.6 5V to
5.5V V
range. The inputs and outputs are high im ped-
