Datasheet
The NC7S00 is a single 2-Input high performance CMOS NAND Gate. Advanced Silicon Gate CMOS fabrication assures high speed and low power circuit operation over a broad VCC range. ESD protection diodes inherently guard both inputs and output with respect to the VCC and GND rails. Three stages of gain between inputs and output assures high noise immunity and reduced sensitivity to input edge rate.
