双D触发器具有置位和复位高性能硅栅CMOS Dual D Flip−Flop with Set and Reset High−Performance Silicon−Gate CMOS
High−Performance Silicon−Gate CMOS
The MC74HC74A is identical in pinout to the LS74. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device consists of two D flip−flops with individual Set, Reset,
and Clock inputs. Information at a D−input is transferred to the corresponding Q output on the next positive going edge of the clock input. Both Q and Qoutputs are available from each flip−flop. The Set and Reset inputs are asynchronous.
