ON Semiconductor NC7ST02 User Manual

TinyLogic HST 2-Input NOR Gate

NC7ST02

Description

The NC7ST02 is a single 2−Input high performance CMOS NOR Gate, with TTL−compatible inputs. Advanced Silicon Gate CMOS fabrication assures high speed and low power circuit operation. ESD protection diodes inherently guard both inputs and output with respect to the V immunity and reduced sensitivity to input edge rate. The TTL−compatible inputs facilitate TTL to NMOS / CMOS interfacing. Device performance is similar to MM74HCT but with current drive of HC / HCT.
