All the device inputs should be connected to a valid logic levels, even on the unused elements.
This means that to divide by 2, the set and clear must be pulled up or connected to the rail, not to ground. 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 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 ] and the other has RD [asynchronous reset-direct input active LOW ] on the diagram.
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? Home Questions Tags Users Unanswered.

Douwe66 1, 6 Likewise the series:. Yes, you can use a to divide by two. I am hobbyist and am looking to reduce signal frequency using D type flip flops. Sign up using Email and Password.

If they float to a middle voltage, the chip can draw excessive supply current and overheat. The other difference you already mentioned are the set and reset pin. Could this be done using 74HC74? When reset is active the output pins Q and Qbar have a fixed state.
The difference between the series and series is amongst other things the voltage rating:. I have a circuit diagram for a IC but I would like to use a 74HC74 instead and I do not understand if it is possible.
Furthermore the pinout differs, so take a look at the datasheet for the right location of the pins! 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.
Confirming Douwe, only the inputs, don’t connect any outputs to ground or rail. Noting the above mentioned points, datashet could easily interchange the two flipflops.
