CLOCK DRIVER QUAD D-TYPE FLIP-FLOP WITH MATCHED PROPAGATION DELAYS

The MC74F803 is a high-speed, low-power, quad D-type flip-flop featuring separate D-type inputs, and inverting outputs with closely matched propagation delays. With a buffered clock (CP) input that is common to all flip-flops, the F803 is useful in high-frequency systems as a clock driver, providing multiple outputs that are synchronous. Because of the matched propagation delays, the duty cycles of the output waveforms in a clock driver application are symmetrical within 1.0 to 1.5 nanoseconds.
