Clock Driver
Quad DĆType FlipĆFlop
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.
• Edge-Triggered D-Type Inputs
• Buffered Positive Edge-Triggered Clock
• Matched Outputs for Synchronous Clock Driver Applications
• Outputs Guaranteed for Simultaneous Switching
