It has the same high speed performance of LSTTL combined with true CMOS low power consumption. These four flip-flops are controlled by a clock input (CLOCK) and a clear input (CLEAR). The information data applied to the D inputs (1D to 4D) are transfered to the outputs (1Q to 4Q and 1Q to 4Q) on the positive-going edge of the clock pulse. The reset function is accomplished when the clear input is taken low and all Q outputs are kept low regardless of other input conditions. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
