MAX395EAG-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX395EAG-T is a serially controlled, low-voltage, 8-channel single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features eight independently controlled switches with an on-resistance of 100Ω maximum, matched to 5Ω maximum between channels. The device supports dual supplies from ±2.7V to ±8V or a single supply from +2.7V to +16V. It utilizes an SPI/QSPI/Microwire-compatible serial interface and includes an asynchronous RESET input. The component operates within a temperature range of -40°C to +85°C and is housed in a 24-pin SSOP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Serially controlled architecture allowing independent management of eight SPST switches via standard digital interfaces

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EAG-T' against official manufacturer documentation to confirm tape-and-reel packaging and industrial temperature grade specifications. Ensure compatibility with existing serial interface protocols such as SPI or Microwire before integration. Cross-reference the part number with current Analog Devices databases to confirm active status and availability constraints.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring multiple independently controlled analog paths with minimal board space. The serial interface reduces pin count compared to parallel-controlled alternatives. Verify that the 100Ω on-resistance meets the signal integrity requirements of the application. Consider the ±5V supply compatibility if interfacing with TTL/CMOS logic levels directly.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX395 belongs to the Maxim Integrated family of low-voltage analog switches designed for compact, high-density applications. It serves as a pin-compatible alternative to industry-standard devices like the MAX335, facilitating easier upgrades or design iterations. The series emphasizes low power consumption and robust ESD protection, making it suitable for portable and industrial environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX395EWG+T is a verified pin-compatible replacement offering identical functionality in a SOIC-24 package. Designers should verify footprint dimensions and thermal characteristics when substituting between SSOP and SOIC packages. Ensure that the replacement variant maintains the required serial interface timing and voltage levels.
