alternative for LM324 as a comparator

hi frnds..
I'm using LM324 as comparator for my Line follower Robot..
LM324 has only 4 output for 4 sensors..but I wanna use 8 sensors for my robot..
can u please suggest me an IC which supports 8 sensor circuit..

Why don't you start with a real comparator, like an LM339?

The LM339 has open-collector outputs, so you'll need to use pull-up resistors on the outputs.

What's the matter with using two quad comparator ICs?
