D触发器三态同相输出

These circuits are positive-edge triggered D-type flip-flops with an enable input. The "HC377, "HC378, and "HC379 devices are similar to "HC273, "HC174, and "HC175 respectively, but feature a latched clock enable G instead of a common clear.

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 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
