A signal on the D INPUT is transferred on the Q OUTPUT during the positive going transition of the clock pulse. CLEAR and PRESET are DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC74B1R M74HC74M1R T&R M74HC74RM13TR M74HC74TTR independent of the clock and accomplished by a low on the appropriate input. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
