How would such a circuit be different? The other difference you already mentioned are the set and reset pin. Yes, you can use a to divide by two. For the 74HC74 it is active low, this means that you need to connect them to VDD if you want the flip flop to operate.

Greg 1 6. The difference between the series and series is amongst other things the voltage icc From looking at the functional diagram in the specifications, they are essentially the same other then that one has CD [asynchronous clear-direct input active HIGH catasheet and the other has RD [asynchronous reset-direct input active LOW ] on the diagram.
When reset is active the output pins Q and Qbar have a fixed state. I have catasheet circuit diagram for a IC but I would like to use a 74HC74 instead and I do not understand if it is possible.

I am hobbyist and am looking to reduce signal frequency using D type flip flops. The functionality is the same after all. Download a data sheet for both parts and study them carefully for pinout and pin function, IIRC the packages are not pin-compatible, so you will have to change the pin numbers as well.
I want to construct the following diagram using 74HC74 instead of How would such datashete circuit be different? If they float to a middle voltage, the chip can draw excessive supply current and overheat. This means that to divide by 2, the set and clear must be pulled up or connected to the rail, not to ground.

The difference between the series and series is amongst other things the voltage rating:. Outputs should be left unconnected if not used. Noting the above mentioned points, you could easily interchange the two flipflops.
Given that the asynchronous clear-direct input CD and the asynchronous reset-direct input RD are active low and require rails to function, are there any power saving benefits of connecting the unused inputs to ground vs rails?
