When reset is active the output pins Q and Qbar have a fixed state. BUT the set and reset inputs are active low in thewhereas they are active high in the Take all inputs on unused sections of the device to rail or ground, it datashet matter which, obviously take all used inputs to the correct logic level.

Greg 1 6. The functionality is the same after all. I want to construct the following diagram using 74HC74 instead of Sign up using Email and Password. 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.
Likewise the series:. 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.

Could this be done using 74HC74? Sign up using Facebook.
Outputs should be left unconnected if not used. To confirm does “Take all inputs on unused sections of the device 741112 rail or ground” mean that all pins which are not part of the main circuit should be connected to either ground or rail? 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.
Douwe66 1, 6 The difference between the series and series is amongst other things the voltage rating:. This means that to divide by 2, the set and clear must be pulled up or connected to the rail, not to ground.
The other difference you already mentioned are the set and reset pin. If they float to a middle voltage, the daasheet can datssheet excessive supply current and overheat. 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: How would such a circuit be different?

Email Required, but never shown. All the device inputs should be connected to a valid logic levels, even on the unused elements. No, only all the inputs of the dataxheet should be connected to either rail or ground.
