I am trying to build a clock divide by two circuit using a 74HC74 D-type Flip-Flop.
The circuit is correct, I used it with a 32 MHz clock previously.
I am trying to divide a 40 MHz clock by two. 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? (that is without getting a 20 MHz clock)
Checking the output with my scope, I am not getting 20 MHz (usually 13.4...MHz or some other frequency)
