MAX6816EUS+TG52

Specialized ICS Overview

The MAX6816EUS+TG52 is a single-channel CMOS switch debouncer designed to interface mechanical switches with digital systems. It eliminates both opening and closing bounce by requiring input stability for a preset qualification delay of 40ms typical. The device operates on a single supply from +2.7V to +5.5V, drawing only 6µA typical supply current. It features robust inputs handling ±25V levels and provides ±15kV ESD protection per Human Body Model and IEC 1000-4-2 Air-Gap standards. Undervoltage lockout ensures correct output states upon power-up.

Specialized ICS Feature Summary

• Single-supply operation from +2.7V to +5.5V with 6µA typical supply current
• Robust switch inputs tolerate ±25V levels without damage
• ±15kV ESD protection (HBM) and ±8kV contact discharge (IEC 1000-4-2)
• No external components required; includes internal pullup resistors

Specialized ICS Applications

• Microprocessor switch interfacing
• Industrial instruments
• Portable instruments
• Membrane keypads

Specialized ICS Procurement Notes

Verify the ordering suffix '+T' indicates lead-free/RoHS-compliant packaging as specified in the datasheet. Confirm the package code 'U4' corresponds to the SOT143-4 footprint. Ensure the temperature range matches the 'E' grade (-40°C to +125°C). Check for minimum order increments if applicable to the specific distributor channel.

Specialized ICS Selection Notes

Select this component when a single-channel debounce solution is needed for harsh environments requiring high ESD immunity. The SOT143-4 package is suitable for space-constrained portable designs. Compare against the MAX6817 for dual-channel or MAX6818 for octal bus interfacing requirements. Ensure the system voltage remains within the 2.7V to 5.5V operating range.

Specialized ICS Part Context

This part belongs to the MAX6816/MAX6817/MAX6818 family of CMOS switch debouncers manufactured by Maxim Integrated (now Analog Devices Inc.). The MAX6816 specifically denotes the single-channel variant, while the MAX6817 offers dual channels and the MAX6818 provides an octal configuration with data bus compatibility.

Specialized ICS Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX6816EUS-T for leaded versions. For multi-channel needs, consider the MAX6817EUT-T (dual) or MAX6818EAP (octal). Verify that any substitute maintains the ±25V input tolerance and ±15kV ESD protection specifications.
