MAX395EWG+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX395EWG+T is an 8-channel, serially controlled, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a 24-pin Wide SOIC package and operates with dual supplies from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device provides an on-resistance of 100Ω maximum, matched between switches to 5Ω maximum, with flatness of 10Ω maximum over the signal range. Switching times are typically 200ns for turn-on and 200ns for turn-off, with a maximum of 400ns. Off leakage current is 0.1nA at +25°C. The serial interface supports SPI™/QSPI™ and Microwire™ standards.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this variant. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the component meets RoHS3 compliance requirements for environmental regulations. Cross-reference the 24-SOIC physical dimensions against your PCB footprint specifications prior to integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage operation down to 2.7V. The serial interface reduces pin count compared to parallel-controlled switches. Verify that the 100Ω on-resistance meets the signal integrity requirements of the target circuit. Consider the -40°C to +85°C operating temperature range for industrial environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX395 is electrically equivalent to two MAX391 quad switches controlled by a serial interface. It serves as a low-cost solution for multiplexing and signal routing in space-constrained designs. The device simplifies system architecture by integrating shift registers and logic translators into a single package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX395 is pin-compatible with the MAX335. Designers may consider the MAX349 or MAX350 for multiplexer-specific applications requiring improved programming speed.
