MAX349CAP+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX349CAP+T is an 8-channel serially controlled analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with dual supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device features bidirectional signal paths with a maximum on-resistance of 100Ω and a match of 16Ω. It utilizes a SPI/QSPI/MICROWIRE-compatible serial interface for control. The component is housed in a 20-pin SSOP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with existing system voltage rails and serial communication protocols before integration. Confirm RoHS compliance status through manufacturer certificates.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring multiple independently controlled analog switches managed via a serial bus. Consider the supply voltage requirements and thermal performance limits relative to the application environment. Evaluate pin count and package constraints during layout planning.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX349/MAX350 family of low-voltage multiplexers. The MAX349 variant provides eight separate SPST switches, whereas the MAX350 offers two dual 4-to-1 muxes. Both share identical control logic and electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX350CAP+T serves as a functional alternative within the same series, offering dual 4-channel configuration instead of eight separate switches while maintaining identical serial interface and electrical specifications.
