Analog Switches, Multiplexers, Demultiplexers datasheet and documents for MAX389EWG+

MAX389EWG+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX389EWG+ is a dual SP4T analog switch manufactured by Analog Devices Inc./Maxim Integrated, housed in a 24-SOIC surface-mount package. It operates with dual supplies ranging from ±4.5V to ±18V and features a maximum on-resistance of 3 kΩ per channel. The device exhibits a channel-to-channel on-resistance matching of 300 Ω, ensuring signal integrity across multiple paths. Key electrical characteristics include a maximum charge injection of 55 pC and off-state leakage current limited to 500 pA. Switching times are specified at a maximum of 1.5 µs for turn-on and 1 µs for turn-off. The component supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'WG+' against the manufacturer's official datasheet to confirm the 24-SOIC package variant and lead-free compliance status. Cross-reference the part number with authorized distributors to ensure authenticity, as counterfeit components may lack specified electrical parameters. Confirm availability through official channels given potential supply chain fluctuations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual four-to-one switching functionality is required within space-constrained designs. Ensure the system voltage does not exceed the ±18V absolute maximum rating. Consider the 3 kΩ on-resistance impact on signal attenuation for high-impedance sources. Verify that the 55 pC charge injection meets the noise requirements of the connected circuitry.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX388/MAX389 family of analog switches, designed for general-purpose signal switching. The MAX389 specifically provides two SP4T switches, whereas the MAX388 offers a single 8:1 mux configuration. Both share similar electrical characteristics but differ in pinout and application flexibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX388CWG+ is a related device within the same family but offers different switching topology (8:1 mux vs. dual SP4T). Direct pin-compatible replacements should be verified against the official datasheet for equivalent on-resistance and voltage ratings.
