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) DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC76B1R M74HC76M1R T&R M74HC76RM13TR M74HC76TTR 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.
