MAX349CWN+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX349CWN+T is an 8-channel serially controlled multiplexer in a 20-pin SSOP package. It operates from dual supplies of ±2.7V to ±8V or a single supply of +2.7V to +16V. The device features bidirectional analog switches with a maximum on-resistance of 100Ω and off-leakage current of 0.1nA at +25°C. It supports SPI/QSPI/MICROWIRE interfaces, includes an asynchronous RESET input, and provides >2kV ESD protection. The commercial temperature range is 0°C to +70°C.

Compatible with SPI, QSPI, and MICROWIRE protocols

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) rather than extended or military grades. Confirm the '+T' designation corresponds to tape-and-reel packaging as specified in the manufacturer's ordering information. Cross-reference the pinout for the 20-lead SSOP format to ensure mechanical compatibility with the target PCB footprint.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer with low leakage and rail-to-rail operation is required. Ensure the system voltage falls within the +2.7V to +16V single-supply or ±2.7V to ±8V dual-supply limits. Verify that the host controller supports the required three-wire serial interface timing constraints for reliable data shifting.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX349/MAX350 family of low-voltage multiplexers. The MAX349 variant provides eight individually controlled channels, whereas the MAX350 offers two independent four-channel sets. Both share identical control logic and electrical characteristics, differing only in channel count and pin assignment for the additional outputs.
