(TOP VIEW)
These monolithic, positive-edge-triggered flip-
flops utilize TTL circuitry to implement D-type
flip-flop logic with a direct clear (CLR) input.
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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input voltage ratings may be exceeded provided the input current ratings are observed.
