SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN) BALANCED PROPAGATION DELAYS: tPLH tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 02 DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HC02B1R M74HC02M1R T&R M74HC02RM13TR M74HC02TTR DESCRIPTION The M74HC02 is an high speed CMOS QUAD 2-INPUT NOR GATE fabricated with silicon gate C2MOS technology. The internal circuit is composed of 3 stages including buffer output, which enables high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
