Outputs should be left unconnected if not used. If they float to a middle voltage, the chip can draw excessive supply current and overheat. Yes, you can use a to divide by two.
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. This means that to divide by 2, the set and clear must be pulled up or connected to the rail, not to ground.

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.

Email Required, but never shown. Take all inputs on unused sections of the device 74112 rail or ground, it doesn’t matter which, obviously take all used inputs to the correct logic level. I am hobbyist and am looking to reduce signal frequency using D type flip flops. 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 have to change the pin numbers as well.
What is the difference between and ICs? Noting the above mentioned points, you could easily interchange the two flipflops. The functionality is the same after all.
How do they differ from ? Furthermore the pinout differs, so take a look at kc datasheet for the right location of the pins! Post as a guest Name.
Could this be done using 74HC74? Confirming Douwe, only the inputs, dafasheet connect any outputs to ground or rail. BUT the set and reset inputs are active low in thewhereas they are active high in the 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?
The difference between the series and series is amongst other things the voltage rating:. Greg 1 6.

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. When reset is active the output pins Q and Qbar have a fixed state. Home Questions Tags Users Unanswered.
How would such a circuit be different? All the device inputs should be connected to a valid logic levels, even on the unused elements. Sign up using Facebook.
