Description for the SN74HC273
The SNx4HC273 devices are positive-edge-triggered D-type flip-flops with a direct active low 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 (CLK) pulse. Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.
