Hi Ronnie,
Apologies for the delayed of response. Before we could recommend parts, I need few more details about your applications:
1. What signal levels will the comparator input see?
2. Do you need any specific output logic level?
3. You mentioned latches - does this mean that you want the output of the comparator to stay at a certain level until they intervene?
4. The rise and fall times of the waveform to be compared are very fast but the signal itself is not. When do you want to detect the change on the rising/falling edge or when the signal has reached its high/low value?
5. Is the input signal being compared to a set value or to another changing signal?
If you could share any other applications data, it would also be helpful.
Best regards,
Emman
