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 76 DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HC76B1R M74HC76M1R T&R M74HC76RM13TR M74HC76TTR DESCRIPTION The M74HC76 is an high speed CMOS DUAL J-K FLIP FLOP WITH CLEAR fabricated with silicon gate C2MOS technology. Depending on with the logic level at J and K inputs, this device changes state on the negative going transition of clock pulse (CK). CLEAR (CLR) and PRESET (PR) are independent of the clock and are accomplished by a logic low on the corresponding input. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
