description
These monolithic, positive-edge-triggered flipflops utilize TTL circuitry to implement D-type
flip-flop logic with a direct clear (CLR
Information at the data (D) inputs meeting setup
time requirements is transferred to outputs on the
positive-going edge of the clock pulse. Clock
triggering occurs at a particular voltage level and
is not directly related to the transition time of the
positive-going pulse. When the clock (CLK) input
is at either the high or low level, the D-input signal
has no effect at the output.
