MAX335EWG

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX335EWG is a serial-controlled analog switch featuring eight independently controlled single-pole-single-throw (SPST) channels housed in a 24-pin Wide SO package. It operates with dual power supplies ranging from ±4.5V to ±20V and handles rail-to-rail analog signals up to ±15V. The device utilizes an SPI-compatible three-wire serial interface for data input, allowing multiple units to be daisy-chained. Electrical characteristics include a typical on-resistance of 100Ω, maximum turn-on/turn-off times of 400ns, and low off-capacitance of 2pF. The component supports an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Eight individually addressable SPST switches managed via a serial digital interface
• SPI-compatible communication protocol supporting daisy-chain configurations
• Rail-to-rail signal handling capability with constant on-resistance across the analog range
• Internal shift registers reset to zero upon power-up to ensure all switches remain off

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EWG confirms the Wide SO package and -40°C to +85°C operating temperature range. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the source document matches the exact part number to avoid confusion with other package variants like TSSOP or DIP.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact solution requires multiple analog switches controlled by a microcontroller via a serial bus. The wide supply voltage range accommodates various analog signal levels. Consider the 100Ω on-resistance and 2pF off-capacitance for high-frequency signal integrity requirements. Verify that the SPI timing parameters align with the host processor's clock speeds.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX335 family of serial-controlled analog switches. It functions as an equivalent to two DG211 quad switches but offers simplified control through a serial interface. The family includes variants with different packages and temperature ratings, such as the CNG for commercial use and MRG for military specifications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include MAX335C/D, MAX335ENG, and MAX335EUG. These parts share identical electrical functionality but differ in package type or operating temperature range. Verify pin compatibility and thermal performance before substitution.
