I need a divide by 256 circuit. The input frequency will be around 600 Hz. The input will come from a slotted opto isolator. The output will have to drive a small electro magnet that I will place a reverse biased diode across. Not sure how much current I will need, but i have to pick up a reed switch in a existing sensor. To maintain the warranty of the sensor, I have to utilize its internal reed switch for activation rather than to bypass the reed switch.
I didn't want to use a clock for the counter.
I think the 4060 would work, but I'm not real sure if it will survive the back emf from the electromagnet. And I don't know whether there might be an inexpensive IC that is more appropriate. If I had to, I could use a driver external to the 4060. But I'd rather not if possible.
Thank you.
