Douwe66 1, 6 To confirm does “Take all inputs on unused sections of the device to rail or ground” mean that all pins which are not part of the main circuit should be connected to either ground or rail? By datzsheet our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. 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.

Greg 1 6. 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? Yes, you can use a to divide by two. Outputs should be left unconnected if not used. How do they differ from ? 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.

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.

BUT the set and reset inputs are active low in thewhereas they are active high in the All the device inputs should be connected to a valid logic levels, even on the unused elements. 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.

How would such a circuit be different? If they float to a middle voltage, the chip can draw excessive supply current and overheat. Post as a guest Name. The difference between the series and series is amongst other things the voltage rating: Download a data sheet for both parts catasheet 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.

Email Required, but never shown. When reset is active the output pins Q and Qbar have a fixed state. I want to construct the following diagram using 74HC74 instead of Home Questions Tags Users Unanswered. Confirming Douwe, only the inputs, don’t connect any outputs to ground datasyeet rail.

Likewise the series:. The other difference you already mentioned are the set and reset pin.

No, only all the inputs of the circuitry should be connected to either rail or ground. I am hobbyist and am looking to reduce signal frequency using D type flip flops. Could this be done using 74HC74? Furthermore the pinout differs, so take a look at the datasheet for the dataeheet location of the pins! Sign up using Email and Password.

Noting the above mentioned points, you could easily interchange the two flipflops. What is the difference between and ICs?

This means that to divide by 2, the set and clear must be pulled up or connected to the rail, not to ground. The functionality is the same after all. The difference between the series and series is amongst other things the voltage rating:.
