MAX389CWG+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX389CWG+T is a high-speed, low-power analog switch manufactured by Analog Devices under the Maxim Integrated brand. It features four independent SPDT switches housed in a 24-pin SOIC package. The device operates with a single supply voltage ranging from +2.7V to +12V or dual supplies of ±2.7V to ±6V. Key electrical parameters include an on-resistance of typically 10 ohms and a channel-to-channel matching of 0.5 ohms. It supports a bandwidth of 300 MHz and offers low charge injection of 0.5 pC. The component functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CWG+T' against official manufacturer documentation to confirm the tape-and-reel packaging format and lead-free status. Ensure compatibility with standard SOIC-24 footprints during PCB layout. Cross-reference with authorized distributors to confirm current availability and authenticity, as supply chain statuses may vary.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring multiple SPDT switches in a compact surface-mount package. Consider the 300 MHz bandwidth and low on-resistance for high-frequency signal integrity. Verify that the operating voltage range aligns with the system's power rails. Evaluate thermal dissipation requirements based on the expected load current and ambient temperature conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX389 family of analog switches, designed for general-purpose signal switching applications. It is part of Analog Devices' portfolio of mixed-signal integrated circuits. The device complements other switch families by offering a balance of speed, power consumption, and channel count in a standard industrial temperature range package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult official substitution guides for pin-compatible alternatives such as the MAX388 or MAX390 series if different channel counts or specifications are required. Verify that any substitute maintains the same SOIC-24 footprint and electrical characteristics to ensure seamless integration without redesign.
