NC7ST02 TinyLogic HST 2-Input NOR Gate February 1997 Revised August 2004 NC7ST02 TinyLogic HST 2-Input NOR Gate General Description Features The NC7ST02 is a single 2-Input high performance CMOS Space saving SOT23 or SC70 5-lead package NOR Gate, with TTL-compatible inputs. Advanced Silicon Ultra small MicroPak leadless package Gate CMOS fabrication assures high speed and low power High Speed t < 7 ns typ, V = 5V, C = 15 pF PD CC L circuit operation. ESD protection diodes inherently guard Low Quiescent Power I < 1 A typ, V = 5.5V both inputs and output with respect to the V and GND CC CC CC rails. High gain circuitry offers high noise immunity and Balanced Output Drive 2 mA I , 2 mA I OL OH reduced sensitivity to input edge rate. The TTL-compatible TTL-compatible inputs inputs facilitate TTL to NMOS/CMOS interfacing. Device performance is similar to MM74HCT but with the output current drive of HC/HCT.
