MAX6817EUT+T

Specialized ICS Overview

The MAX6817EUT+T is a dual CMOS switch debouncer designed to interface mechanical switches with digital systems. It accepts bouncing inputs and produces clean digital outputs after a preset qualification delay, removing both opening and closing bounce. The device operates on a single supply from +2.7V to +5.5V with a typical supply current of 6µA. It features robust ±25V input handling and ±15kV ESD protection. Undervoltage lockout ensures correct output states upon power-up. Packaged in SOT-23-6, it requires no external components.

Specialized ICS Feature Summary

• Dual-channel debouncing for mechanical switches
• ±15kV Human Body Model and ±8kV IEC Contact Discharge ESD protection
• Robust inputs tolerate ±25V levels exceeding power supplies
• Low supply current of 6µA (typical) at VCC = 5V

Specialized ICS Applications

• Microprocessor switch interfacing
• Industrial instruments
• Portable instruments

Specialized ICS Procurement Notes

Verify the ordering suffix '+T' indicates lead-free/RoHS-compliant packaging as specified in the manufacturer's documentation. Confirm the package type matches the required SOT-23-6 footprint. Ensure the temperature range meets the application requirements for the 'E' suffix (-40°C to +125°C). Check for any specific distributor restrictions or minimum order increments associated with the reel packaging.

Specialized ICS Selection Notes

Select the MAX6817EUT+T when dual independent switch channels are required. Choose this part over the MAX6816 if two channels are needed instead of one. Consider the MAX6818 if octal channels or data bus interfacing with three-state outputs are necessary. Verify that the 40ms debounce duration fits the system timing constraints.

Specialized ICS Part Context

The MAX6817 is part of the MAX6816/MAX6817/MAX6818 family of switch debouncers. While the MAX6816 provides a single channel and the MAX6818 offers eight channels with additional control features, the MAX6817 specifically provides two independent debounced outputs. All variants share similar electrical characteristics, including ESD protection and low power consumption.
