Hello Chaitanya,

Can you clarify your request? Most of the combination comparator and op-amp devices (LM392) are too slow for 10MHz.

What are you trying to accomplish?

Here I am trying to implement bidirectional functionality using the above schematic. The reference voltage for the comparatar will be 70% of (1.8 or 3.3 or 5 ). The input to the comparatar will be at a frequency of 10 Mhz. Will the comparator mentioned in the schematic can be used there or not
