Hey all,
I'm looking to make a divide by N circuit. I really don't know what chip I should be looking at. I'd prefer something with a fast response time, this divide by N will go onto a trigger to another circuit.
I was thinking something along the lines of an up/down counter. I currently have an SN74AS867 at my disposal - http://www.ti.com/lit/ds/symlink/sn74as867.pdf. My thought is to set the input to a set binary number - say 250 - and then count up. Tell the chip to count up and once the counter gets to 255, use the /RCO to load in the 250 and then use an inverter to invert the /RCO to use that as my actual trigger.
I drew a quick schematic of what I'm thinking. It will be programmable via DIP switches and pull up resistors.
Would there be a better/faster way for me to achieve the divide by n?
Thanks,
Matt
