 HST 2-Input NOR Gate

General Description

The NC7ST02 is a single 2-In put high pe rform ance C MOS
NOR Gate, with TT L-compatible inputs. A dvanced Silicon
Gate CMOS fabrication assures high speed and low power
circuit operation. ES D protection diodes inherently g uard
both inputs and outpu t with respect to the V

CC

and GND

rails. High gain circuitry offers high noise immunity and
reduced sensitivity to input edge rate. The TTL-compatible
inputs facilitate TTL to NMOS/CMOS inte rfacing. Device
performance is similar to M M74HCT but w ith ½ the outp ut
current drive of HC/HCT.
