General Description
The NC7SZ27 is a single 3-Input NOR Gate from
Fairchild’s Ultra High Speed Series of TinyLogic
device is fabricated wi th advanced CMOS technology to
achieve ultra high spe ed w ith h i gh out put drive while mai ntaining low static power dissipation over a very broad V
operating range. Th e device is specified to operate ov er
the 1.65V to 5.5V V
high impedance when V
up to 7V independent of V
UHS 3-Input NOR Gate
Features
