– Dual J-K flip-flop with set and reset; negative-edge trigger – ChipDB
Home Questions Tags Users Unanswered. Furthermore the pinout differs, so take a look at the datasheet for the right location of the pins!
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. Post as a guest Name.
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.
Datasjeet Required, but never shown. Take all inputs on unused sections of the device to rail or ground, it doesn’t matter which, obviously take all used inputs to the correct logic level. How would such a circuit be different? The functionality is the same after all.

Confirming Douwe, only the inputs, don’t connect any outputs to ground or rail. Yes, you can use a to divide by two. The difference between the series and series is amongst other things the voltage rating: 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. All the device inputs should be connected to a valid logic levels, even on the unused elements.
Noting the above mentioned points, you could easily interchange the two flipflops. Likewise the series:.
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 dayasheet to change the pin numbers as well. 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?
Outputs should be left unconnected if not used. What is the difference between and ICs?

I want to construct the following diagram using 74HC74 instead of When reset is active the output pins Q and Qbar have a fixed state. Greg 1 6. Sign up using Email and Password.
Sign up using Facebook. 744112 am hobbyist and am looking to reduce signal frequency using D type flip flops.
Could this be done using 74HC74? This means that to divide by 2, the set and clear must be pulled up or connected to the rail, not to ground. Sign up or log in Sign up using Google. The other difference you already mentioned are the set and reset pin.
