General Description
The NC7WZ32 is a dual 2-Input OR Gate fro m Fairchild’s
Ultra High Speed Series of TinyLogic
cated with advanced CMOS 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
range. The inputs and output are high impedance
