Dual D- type flip- flop with set and reset. If the pulse width doesn’t meet the specs in the datasehet datasheet, it might not be getting every clock. They need to stay high when not used and go momentarily low to perform their defined function. Final question for this thread.

Am I misunderstanding something? Mar 14, 20, 5, You May Also Like: May 8, 4. MHz or some other frequency. The datasheet I read had the ‘typical’ maximum frequency of the clock frequency as 69MHz at 5v. I’m quite surprised that the HC doesn’t cope with 40Mhz.

The circuit is correct, I used it with a 32 MHz clock previously. If not, can anybody recommend an IC?

That makes perfect sense now, I did get the chop working when making the SET pin low. Check our stock now! Of course I can set a pin to be momentary high or low — I keep thinking in terms of LOW being floating PHILIPS – Dual D- type flip- flop with set and reset; positive- edge trigger, alldatasheet, datasheet, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes, triacs, and other semiconductors.
