MAX393CUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX393CUE+ is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four independent channels with a maximum on-resistance of 35 ohms and channel-to-channel matching of 300 milliohms. The device operates on a single supply voltage ranging from 3V to 15V or dual supplies of ±3V to ±8V. Key electrical characteristics include a maximum switch time of 130ns for turn-on and 75ns for turn-off, with a charge injection of 2pC. It is housed in a 16-TSSOP package and supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CUE+ against the official datasheet to confirm the commercial temperature grade and lead-free status. Ensure the 16-TSSOP footprint matches the target PCB layout. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference the manufacturer part number with any obsolete variants if replacing older designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with low distortion and fast switching speeds. Compare the 35-ohm on-resistance against load requirements to ensure minimal signal attenuation. Verify that the 3V to 15V single-supply range aligns with the system power rails. Consider the 0°C to 70°C operating range for environmental compatibility.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX393 belongs to the Maxim Integrated family of precision analog switches. It serves as a standard solution for general-purpose signal switching applications requiring multiple channels. The device complements other multiplexer and demultiplexer offerings in the portfolio, providing a balance of performance and pin count for embedded control systems.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX393EUE+ is a verified equivalent offering the same functional specifications but rated for an extended industrial temperature range of -40°C to 85°C. Both devices share identical pinouts and electrical parameters, allowing for direct substitution if thermal conditions require the wider range.
