Hello????
I asked "
what's connected to the input of the comparator [that needs comparing], and got the reply:

It does not have a comapritor.
So are you saying you are interfacing a 'comparitor', via a comparator to your 89C51?
I'm confused now! Normally you connect into the comparator input, a transducer of some kind (what I was asking about). But I've not heard of a comparitor connected to the input of a comparator. What kind of signal does a comparitor provide to the comparator?
Maybe you don't need a comparator at all and you can just send signal to the 89C51's A-to-D converter instead, and do the comparatoring in software?
