General Description
The NC7WZ08 is a dual 2-Input AND Gate from 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
