description
This monolithic, positive-edge-triggered flip-flop utilizes TTL circuitry to implement D-type flip-flop logic with a
direct clear (CLR) input. Information at the data (D) inputs meeting the setup time requirements is transferred
to the 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.
The SN74F174A is characterized for operation from 0°C to 70°C.

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.
