These positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic. They have an asynchronous clear input, and feature complementary outputs from each flip-flop. Information at the D inputs meeting the setup time requirements is transferred to the Q 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 input is at either the HIGH or LOW level, the D input signal has no effect at the output.
