CD Datasheet(PDF) – Fairchild Semiconductor

Discussion in ‘ Digital Circuit Design ‘ started by testuserabcdefFeb 6, Feb 6, 1. Jul 12, 4. I have a high-speed microcontroller application and I want to hook up a gpio ratasheet on it to an output of a big delay external timer so that I don’t have to hold up the microcontroller cpu just to count a long delay. The perfect approach for me is two monostable multivibrators, because one will be used for the pin and another to refresh the clock on an external flip-flop connected to the micro for other purposes.

Dstasheet tried the CD chip and for the application it works perfectly, however to pull things off, I have to tie 4 items high from the chip itself Icc is a nuisance for PCB development as this forms the letter H under the chip on the board which prevents wires from running through.


I don’t want to use another microcontroller to make the timer itself. Is there a chip like the CD but where the clear input and “B” input are internally tied high instead of offered as pins? I also don’t want to leave the inputs floating as unpredictable results can happen. Feb 6, 2.

Jun 19, 2, There are many ways you can implement delays without going into a dedicated delay loop. Invest the time to learn how to fix this in software, you will not regret it. Dtasheet 6, Feb 7, Apr 11, 3, 1, Feb 9, Apr 4, Nice if it can be every millisecond, for example.

Makes calculating the timing easier. But can be any fixed rate. This runs all the time. Then, in the interrupt routine have a variable which is your virtual “timer” – you can have as many of these as you like as you like.


Have a flag a bit that controls this timer from the code outside the interrupt. When the flag is clear timer stoppedset the register to your timing datashret. When the flag is set timer running decrement the register every interrupt. When the register reaches zero – the time delay is complete and you stop decrementing.

Only a few lines of code.
