Description

The MAX***6/MAX***7/MAX***8 are single, dual, and octal switch debouncers that provide clean interfacing of mechanical switches to digital systems. They accept 

one or more bouncing inputs from a mechanical switch and produce a clean digital output after a short, preset qualification delay. Both the switch opening bounce and the switch closing bounce are removed. Robust witch inputs handle ±*5V levels and are ±*5kV ESD-protected for use in harsh industrial environments. They feature single-supply operation from *2.7V to *5.5V. Undervoltage lockout circuitry ensures the output is in the correct state upon power-up.The single MAX***6 and dual MAX***7 are offered in SOT packages and require no external components. Their low supply current makes them ideal for use in portable equipment.The MAX***8 octal switch debouncer is designed for data-bus interfacing. The MAX***8 monitors switches and provides a switch change-of-state output (CH), simplifying microprocessor (µP)polling and interrupts. Additionally, the MAX***8 has three-state outputs controlled by an enable (EN) pin, and is pin-compatible with the LS**3 octal latch (except for the CH pin), allowing easy interfacing to a digital data bus.
