八进制,十六进制和四D型触发器与时钟使能 OCTAL, HEX, AND QUAD D-TYPE FLIP-FLOPS WITH CLOCK ENABLE
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
