8 pcs, dual d flip−flop with set and reset ( 74HC74A )
8 pcs of Dual D Flip Flop with Set and Reset
The 74HC74A is identical in pin out to the LS74. The device
inputs are compatible with standard CMOS outputs; with pull up
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 Q outputs are available from each flip flop. The Set
and Reset inputs are asynchronous.
