Could this be done using 74HC74? Likewise the series:.
Sign up using Email and Password. 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?
The difference between the series and series is amongst other things the voltage rating:. How would such a circuit be different? 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.

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. This means that to divide by 2, the set and clear must be pulled datashret or connected to the rail, not to ground. Yes, you can use a to divide by two.

No, only all the inputs of the circuitry should be connected to either rail or 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.
If they float to a middle voltage, the chip can draw excessive supply current and overheat. Sign up or log in Sign up using Google.
Douwe66 1, 6 The other difference you already mentioned are the set and reset pin.
Confirming Douwe, only the inputs, don’t connect any outputs to ground or rail. 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 How do they differ from ?
Outputs adtasheet be left unconnected if not used.
Greg 1 6. Email 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. I want to construct the following diagram using 74HC74 instead of All the device inputs should be connected to a valid logic levels, even on the unused elements.

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 datasneet Furthermore the pinout differs, so take a look at the datasheet for ratasheet right location of the pins!
Noting the above mentioned points, you could easily interchange the two flipflops. When reset is active the output pins Q and Qbar have a fixed state.
