The SN74ALS273N is an octal positive-edge-triggered D-type Flip-flop with clear and single-rail outputs. It utilizes TTL circuitry to implement D-type flip-flop logic with a direct-clear (CLR\) input. Information at the data (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 CLK is at either the high or low level, the D input signal has no effect at the output.

• Buffered clock and direct-clear inputs
• Individual data input to each flip-flop
