General Description

The NC7S00 is a sing le 2-Input high perfor mance CMOS
NAND Gate. Advanced Silicon Gate CMOS fabrication
assures high speed and low po wer cir cuit oper atio n over a
broad V

both inputs and outpu t with respect to the V
rails. Three stages of gain between inputs and output

assures high noise immunity and reduced sensitivity to
input edge rate.
