Hex / Quadruple D-type Flip-Flops (with clear)

●These positive-edge-triggered flip-flops utilize TTL circuitry toimplement D-type flip-flop logic. All have a direct

●clear input, and the HD74LS175 features complementary outputs from each flip-flops. 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 outputs.
