MAX6816/MAX6817/ 15kV ESD-Protected, Single/Dual/Octal, MAX6818 CMOS Switch Debouncers General Description Benefits and Features The MAX6816/MAX6817/MAX6818 are single, dual, and Switch Debouncer Integration Simplifies System octal switch debouncers that provide clean interfacing Interface to Mechanical Switches of mechanical switches to digital systems. They accept Single-Supply Operation from +2.7V to +5.5V one or more bouncing inputs from a mechanical switch No External Components Required and produce a clean digital output after a short, preset Single (MAX6816), Dual (MAX6817), and qualification delay. Both the switch opening bounce Octal (MAX6818) Versions Available and the switch closing bounce are removed. Robust 6A Supply Current switch inputs handle 25V levels and are 15kV Built-In Protection Circuitry Improves System ESD-protected for use in harsh industrial environments. Reliability They feature single-supply operation from +2.7V to +5.5V. Inputs Can Exceed Power Supplies up to 25V Undervoltage-lockout circuitry ensures the output is in ESD Protection for Input Pins the correct state upon power-up. - 15kVHuman Body Model The single MAX6816 and dual MAX6817 are offered in - 8kVIEC 1000-4-2, Contact Discharge SOT packages and require no external components. - 15kVIEC 1000-4-2, Air-Gap Discharge Their low supply current makes them ideal for use in Octal Version (MAX6818) Provides Direct Data portable equipment. Bus Interface The MAX6818 octal switch debouncer is designed for Three-State Outputs for Directly Interfacing to data-bus interfacing. The MAX6818 monitors switches P (MAX6818) and provides a switch change-of-state output (CH), Switch Change-of-State Output Simplifies Polling simplifying microprocessor (P) polling and interrupts. and Interrupts (MAX6818) Additionally, the MAX6818 has three-state outputs Pin-Compatible with LS573 (MAX6818) controlled by an enable (EN) pin, and is pin-compatible Ordering Information with the LS573 octal latch (except for the CH pin), allowing easy interfacing to a digital data bus.
