Part Manufacturer: Maxim


Part Description: MAX6816 17 18 DS

Part Details:

19-4770; Rev 2; 12/05 ±15kV ESD-Protected, Single/Dual/Octal, CMOS Switch Debouncers MAX6816/MAX6817/MAX6818 General Description Features The MAX6816/MAX6817/MAX6818 are single, dual, and Robust Inputs can Exceed Power Supplies octal switch debouncers that provide clean interfacing up to ±25V of mechanical switches to digital systems. They acceptone or more bouncing inputs from a mechanical switch ESD Protection for Input Pins and produce a clean digital output after a short, preset ±15kV--Human Body Model qualification delay. Both the switch opening bounce ±8kV--IEC 1000-4-2, Contact Discharge and the switch closing bounce are removed. Robust ±15kV--IEC 1000-4-2, Air-Gap Discharge switch inputs handle ±25V levels and are ±15kV ESD- Small SOT Packages (4 and 6 pins) protected for use in harsh industrial environments. Theyfeature single-supply operation from +2.7V to +5.5V. Single-Supply Operation from +2.7V to +5.5V Undervoltage lockout circuitry ensures the output is in Single (MAX6816), Dual (MAX6817), and Octal the correct state upon power-up. (MAX6818) Versions Available The single MAX6816 and dual MAX6817 are offered inSOT packages and require no external components. No External Components Required Their low supply current makes them ideal for use in 6µA Supply Current portable equipment. Three-State Outputs for Directly Interfacing The MAX6818 octal switch debouncer is designed fordata-bus interfacing. The MAX6818 monitors switches Switches to µP Data Bus (MAX6818) and provides a switch change-of-state output (CH), Switch Change-of-State Output Simplifies simplifying microprocessor (µP) polling and interrupts. Polling and Interrupts (MAX6818) Additionally, the MAX6818 has three-state outputs con-trolled by an enable (EN) pin, and is pin-compatible Pin-Compatible with LS573 (MAX6818) with the LS573 octal latch (except for the CH pin),allowing easy interfacing to a digital data bus.
