I am trying to divide a 40 MHz clock by two.
Once again, thank you. Of course I can datssheet a pin to be momentary high or low — I keep thinking in terms of LOW being floating The datasheet I read had the ‘typical’ maximum frequency of the clock frequency as 69MHz at 5v.

I have taken your advice and added a pull-up resistor. MHz or some other frequency. Media New media New comments Search media. May 8, 1. If the pulse width doesn’t meet the specs in the 74’s datasheet, it might not be getting every clock.
Is it not possible to use this IC as a dxtasheet SR flip-flop?

They need to stay high when not used and go momentarily ddatasheet to perform their defined function. Do you recommend the CD FF? I’m however having problems understanding the IC.
I have even tried this setup using an online circuit simulator, of course, it does not work. Did you look at the Data Sheet Truth Table? The circuit is correct, I used it with a 32 MHz clock previously. Whats the source of this clock? Final question for this thread. Unfortunately, I think this will cause me a problem using the Arduino to send a reset command.
