MAX311CWN

Analog Switches - Special Purpose Overview

The MAX311CWN is a CMOS RF video multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features two independent 4-to-1 multiplexer channels housed in an 18-SOIC surface-mount package. The device operates on a single supply voltage ranging from 9V to 36V or dual supplies of ±4.5V to ±18V. Key electrical specifications include a maximum on-resistance of 250 Ohms and a power dissipation rating of 550 mW. It supports through-break-before-make switching configurations and functions within a commercial temperature range of 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Integrates two independent 4:1 multiplexer circuits for signal routing
• Supports wide single-supply (9V to 36V) and dual-supply operation
• Features CMOS technology for low power consumption
• Includes break-before-make switching capability

Analog Switches - Special Purpose Applications

• Video signal routing and distribution systems
• RF video multiplexing applications
• Test and measurement equipment requiring analog signal switching

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity and datasheet revisions before integration, as the MAX311CWN is listed as obsolete. Confirm that the non-RoHS compliant status aligns with regulatory requirements for the target deployment region. Ensure replacement strategies account for the discontinuation notice issued in April 2019.

Analog Switches - Special Purpose Selection Notes

Select this component only if legacy compatibility with the 18-SOIC footprint and specific voltage ranges is required. Evaluate the MAX311CWE+ as a direct RoHS-compliant alternative if environmental regulations mandate lead-free components. Verify that the 250 Ohm on-resistance meets the signal integrity requirements of the application circuit.

Analog Switches - Special Purpose Part Context

The MAX311CWN belongs to the MAX311 series of CMOS RF video multiplexers produced by Maxim Integrated, now part of Analog Devices Inc. This specific variant utilizes an 18-pin SOIC package and represents an earlier generation of video switching ICs designed for multi-channel signal management in professional audio and video infrastructure.

Analog Switches - Special Purpose Replacement Considerations

The MAX311CWE+ is documented as a direct replacement for the MAX311CWN.
