MAX391EUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX391EUE+T is a precision, quad, single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a single supply voltage ranging from 3 V to 15 V or dual supplies of ±3 V to ±8 V. The device features a maximum on-resistance of 35 Ohms and supports a switching current of 30 mA. Key timing parameters include a maximum turn-on time of 130 ns and a maximum turn-off time of 75 ns. It is housed in a 16-pin SOIC-Narrow package and functions within an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EUE against official datasheets to confirm the SOIC-Narrow 16-pin package and industrial/commercial temperature grade. Confirm RoHS compliance status through manufacturer documentation as '+ ' indicates lead-free packaging. Cross-reference the full part number with authorized distributors to ensure authenticity and traceability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact solution for multiple analog signal paths is required without digital interface complexity. Ensure the system voltage stays within the 3 V to 15 V single supply range. Verify that the 35 Ohm on-resistance meets the signal integrity requirements of the application compared to lower resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX391 family of precision analog switches. It serves as a surface-mount alternative to through-hole variants like the MAX391EPE. The device is designed for general-purpose analog switching where moderate speed and low distortion are prioritized over ultra-low on-resistance.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX391EPE is a documented PDIP replacement variant. Check pin compatibility and thermal performance differences between SOIC-Narrow and DIP packages before substitution.
