SN74LS378N (TEXAS INSTRUMENTS)

The SN74LS378N is a hex D-type Flip-flop with clock enable. It utilizes TTL circuitry to implement D-type flip-flop logic with an enable 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 if the enable input G 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 the clock input is at either the high or low level, the D input signal has no effect at the output. It is designed to prevent false clocking by transitions at the G input. It is guaranteed to respond to clock frequencies ranging from 0 to 30MHz while maximum clock frequency is typically 40MHz. Typical power dissipation is 10mW per flip-flop.
