CLOCK DRIVER
QUAD D-TYPE FLIP-FLOP
WITH MATCHED PROPAGATION DELAYS
The MC74F1803 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 MC74F1803 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 2.0 nanoseconds.
