The SN74F378 is a positive-edge-triggered D-type flip-flop with a clock enable (CLKEN) input. The SN74F378 is similar to the SN74F174 but features a common clock enable 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 positive-going pulse. When the clock (CLK) input is at either the high or low level, the D-input signal has no effect at the output. The SN74F378 is characterized for operation from 0C to 70C. FUNCTION TABLE
