MAX349EAP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX349EAP+T is a serially controlled, low-voltage, 8-channel multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates from dual supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device features an on-resistance of 500 Ohms maximum at 3V operation, with turn-on time up to 600 ns and turn-off time up to 300 ns. It supports rail-to-rail analog signal handling and includes an asynchronous RESET input. The component is housed in a 20-pin SSOP package and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Serial interface compatible with SPI, QSPI, and MICROWIRE standards for daisy-chaining multiple units
• Bidirectional 8-channel SPST switch configuration with rail-to-rail signal handling capability
• Asynchronous reset function that powers up all switches in the off state

Analog Switches, Multiplexers, Demultiplexers Applications

• Serial data-acquisition systems
• Industrial and process-systems control
• Audio signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the '+T' designation aligns with RoHS compliance requirements for your assembly process. Ensure the SSOP-20 footprint matches your PCB layout constraints before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring independent control of eight analog channels via a serial bus. Verify that the 500 Ohm on-resistance at lower supply voltages meets your signal integrity requirements. Consider the bidirectional nature of the switches for flexible circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX349/MAX350 family of serially controlled multiplexers. While the MAX350 offers a dual 4-channel configuration, the MAX349 provides a single 8-channel solution. Both share identical serial interface logic and electrical characteristics, differing primarily in channel count and pinout mapping.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX349CWN is a documented alternative within the same family, offering 18-SOIC packaging. Verify pin compatibility and package dimensions before substitution.
