HD74LS273 Octal D-type Positive-edge-triggered Flip-Flops (with Clear) REJ03D0473–0300 Rev.3.00 Jul.15.2005 The HD74LS273, positive-edge-triggered flip-flops utilize LS TTL circuitry to implement D-type flip-flop logic with 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. When the clock input is at either the high or low level, the D input signal has no effect at the output.
