General Description
The NC7SZ02 is a single 2-Input NOR Gate from Fairchild’s Ultra High Speed Series of TinyLogic
is fabricated with a dvanced CMOS technolo gy to achieve
ultra high speed with high outpu t drive while maintaining
low static power dissipa tion over a very b road V
ing range. The device is specified to operate ove r the 1.8V
to 5.5V V
