The is an octal positive-edge-triggered D-type Flip-flop with clock enable. It is similar to the HC273 devices, but features a latched clock-enable CLKEN\\ input instead of a common clear. 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, if CLKEN\ is low. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When clock is at either the high or low level, the D input has no effect at the output. It is designed to prevent false clocking by transitions at CLKEN\\.
