    so i can't remember the name of this chip but i know what it does. I believe its a type of op amp or maybe a configuration of one, or just its own chip all together.

    it's used for noisy signals, only changing states (between high and low) when a threshold is crossed. so say once it goes high a certain 'low' threshold needs to be crossed, and once it goes low a new 'high' threshold is set. This way noisy signals do not trigger unnecessary multiple triggers

    anyone help?

    Which can be discreet transistors, a specialized chip, a comparator, or an opamp.
