MAX6816EUS+TGA8

Specialized ICS Overview

The MAX6816EUS+TGA8 is a single-channel CMOS switch debouncer manufactured by Analog Devices Inc./Maxim Integrated. It provides clean digital interfacing for mechanical switches by removing both opening and closing bounce signals after a preset qualification delay. The device operates on a single supply voltage ranging from +2.7V to +5.5V and features robust inputs capable of handling ±25V levels with ±15kV ESD protection. It includes undervoltage lockout circuitry to ensure correct output states upon power-up. The component is housed in a 4-pin SOT143 package.

Specialized ICS Procurement Notes

Verify the specific ordering suffix against official documentation, as it dictates RoHS compliance and packaging details. Confirm availability through authorized distributors, noting that minimum order increments may apply to SOT packages. Ensure the procurement channel sources genuine components to maintain specified electrical characteristics and reliability standards.

Specialized ICS Selection Notes

Select this component when interfacing mechanical switches to digital systems requiring high noise immunity and low supply current. The MAX6816 is suitable for portable equipment due to its low power consumption. Verify that the operating temperature range of -40°C to +125°C meets the application requirements and that the SOT143-4 package fits the board layout constraints.

Specialized ICS Part Context

This part belongs to the MAX6816/MAX6817/MAX6818 family of CMOS switch debouncers. While the MAX6816 handles single channels, the MAX6817 offers dual channels, and the MAX6818 provides octal channels with data bus interfacing capabilities. All variants share similar core functionalities regarding debounce timing and input protection.

Specialized ICS Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX6817 (dual) or MAX6818 (octal), though channel counts differ. Other generic switch debouncers may require circuit redesign due to differences in input voltage tolerance, ESD protection levels, or debounce timing specifications.
