The SN74LS175N is a quadruple D-type Flip-flop with clear utilize TTL circuitry to implement D-type flip-flop logic. The LS175 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. This circuit is fully compatible for use with most TTL circuits.
