The SN74LS174N is a hex D-type Flip-flop with clear. It utilizes TTL circuitry to implement D-type flip-flop logic. All have a direct clear input. 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. It is fully compatible for use with most TTL circuits.
