MAX398EGE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398EGE is a high-speed, low-power analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an 8-channel configuration with single-pole single-throw (SPST) topology housed in a 24-pin SSOP package. The device operates on a single supply voltage ranging from 2.7 V to 16 V or dual supplies up to ±8 V. Key electrical parameters include a maximum on-resistance of 100 Ohms, a maximum turn-on/turn-off time of 400 ns, and a maximum power supply current of 20 µA. It supports a continuous DC switch current of 30 mA and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EGE against the official datasheet to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the ordering information matches the required lead times and availability constraints listed in official catalogs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when serial control is preferred over parallel GPIO usage to save microcontroller pins. Consider the 100 Ohm on-resistance limit for signal integrity requirements. Verify that the 400 ns switching speed meets the application timing constraints. Ensure the operating voltage range aligns with the system power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX398 belongs to the Maxim Integrated family of serially controlled analog switches. It is designed to replace parallel-controlled switches in space-constrained designs. The EGE suffix denotes the specific SSOP-24 package variant. This part integrates shift register logic to manage channel selection efficiently.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult the official cross-reference guide for parametrically equivalent parts. Verify pin compatibility and electrical specifications before substitution. Check for package dimension differences if mechanical fit is critical.
