MAX6816EUS-T

Specialized ICS Overview

The MAX6816EUS-T is a single-channel CMOS switch debouncer manufactured by Analog Devices Inc./Maxim Integrated. It provides clean interfacing of mechanical switches to digital systems by removing both opening and closing bounce with a preset qualification delay. 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 offers ±15kV ESD protection per the Human Body Model. The unit is housed in a SOT-143-4 package and supports an operating temperature range of -40°C to +125°C.

Specialized ICS Feature Summary

• Single-supply operation from +2.7V to +5.5V with 6µA typical supply current
• Built-in ±15kV ESD protection (Human Body Model) and ±25V input fault tolerance
• No external components required for switch debouncing integration
• Undervoltage-lockout circuitry ensures correct output state upon power-up

Specialized ICS Applications

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

Specialized ICS Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status as lead-free variants require specific ordering suffixes. Check for availability constraints related to minimum order increments for SOT packages. Ensure storage conditions remain within specified limits prior to assembly.

Specialized ICS Selection Notes

Select this part for applications requiring low-power debouncing of mechanical switches without external components. The -40°C to +125°C temperature range suits industrial environments. Verify that the single-input configuration meets system requirements compared to dual or octal versions.

Specialized ICS Part Context

This component belongs to the MAX6816/MAX6817/MAX6818 family of CMOS switch debouncers. While the MAX6816 handles single inputs, the MAX6817 provides dual channels and the MAX6818 offers octal outputs with data bus interfacing capabilities. All share similar core debouncing and protection features.

Specialized ICS Replacement Considerations

Direct pin-compatible substitutes within the same family include the MAX6817 series for dual-channel needs. Cross-family replacements must match the SOT-143-4 package and voltage/current specifications.
