MAX392C/D

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX392C/D is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It integrates four independent 1:1 switching circuits within a compact 16-SOIC package. The device operates with a single supply voltage ranging from 3V to 15V or dual supplies of ±3V to ±8V. Key electrical specifications include a maximum on-resistance of 35 ohms and a channel-to-channel matching of 300 milliohms. Switching times are specified at a maximum of 130ns for turn-on and 75ns for turn-off. The component exhibits low charge injection of 2pC and leakage current of 100pA, ensuring signal integrity in precision applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix (C or D) to confirm the operating temperature range before ordering. The C variant supports commercial temperatures while the D variant covers industrial ranges. Confirm the package type matches the design requirements. Check for RoHS compliance status as per the latest manufacturer documentation. Ensure the source is an authorized distributor to guarantee authenticity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple independent analog switches are required in a space-constrained design. Compare the 35-ohm on-resistance against load requirements to ensure acceptable voltage drop. Evaluate the 130ns switching time against system speed constraints. Consider the 16-SOIC footprint for PCB layout compatibility. Verify that the 3V minimum supply voltage aligns with the available power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX392 belongs to the Maxim Integrated analog switch family, designed for general-purpose signal switching. It complements other devices in the series offering different channel counts or resistance profiles. The SOIC package provides a balance between pin count and board space efficiency. This component serves as a standard solution for multiplexing applications requiring moderate speed and precision.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX390 or MAX391 if fewer channels are sufficient. Verify that substitute parts maintain similar on-resistance and switching speed specifications. Ensure the replacement supports the same supply voltage range and package dimensions.
