I want to construct the following diagram using 74HC74 instead of Could this be done using 74HC74? How would such a circuit be different? BUT the set and reset inputs are active low in thewhereas they are active high in the Datashedt means that to divide by 2, the set and clear must be pulled up or connected to the rail, not to ground.
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.
Outputs should be left unconnected if not used. 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.
The difference between the series and series is amongst other things the voltage rating:. Furthermore the pinout differs, 7412 take a look at the datasheet for the right location of the pins! The other difference you already mentioned are the set and reset pin. 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. Noting the above mentioned points, you could easily interchange the two flipflops.

How do they differ from ? Greg 1 6. Yes, you can use a to divide by two. 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? No, only all the inputs of the circuitry should be connected to 47112 rail or ground. Confirming Douwe, only the inputs, don’t connect any outputs to ground or rail.
All the device inputs should be connected to a valid logic levels, even on the unused elements.

If they float to a middle voltage, the chip can draw 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?
