Thread starter johnsmith Start date Jun 24, The circuit 7hc74n correct, I used it with a 32 MHz clock previously. I am trying to divide a 40 MHz clock by two.

74HC74N Datasheet, PDF – Qdatasheet

From reading the datasheet, the maximum frequency that the 74HC74 will operate on is 30MHz reliably. Is there an alternative or another way to do this?

MHz or some other frequency. Mikebits Well-Known Member Jun 24, The VHC logic family will operate at your frequency.

Blueteeth Well-Known Member Jun 24, The datasheet I read had the ‘typical’ maximum frequency of the clock frequency as 69MHz at 5v. But the minimum ‘max freq’ is way down to 15Mhz, bizare I’m quite surprised that the HC doesn’t cope with 40Mhz. Whats the source of this clock?

If the pulse datasheeg doesn’t meet the specs in the 74’s datasheet, it might not be getting every clock. Failing that, there are other families you could try.
