The reset feature is asynchronous and active This device is composed of a four-bit register high. The stored data are provided on each output including D-TYPE flip-flops and 3-state buffers. only when both output control inputs (M and N) are The four flip-flops are controlled by a common held low, otherwise the outputs go to the clock input (CLOCK) and a common reset input high-impedance state. (CLEAR). Signals applied to the data inputs (D1 - All inputs are equipped with protection circuits D4) are stored at the respective flip-flops on the against static discharge and transient excess positive going transition of the clock input, only voltage.
