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 circuits housed in an 18-SOIC surface-mount package. The device operates on a single supply voltage ranging from 9 V to 36 V or dual supplies of ±4.5 V to ±18 V. Key electrical specifications include a maximum on-resistance of 250 Ohms, a maximum turn-on time of 100 ns, and a maximum turn-off time of 100 ns. The component supports a maximum power dissipation of 550 mW and functions within a temperature range of 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Integrates two independent 4:1 multiplexer channels for signal routing
• Supports wide single-supply (9V–36V) and dual-supply (±4.5V–±18V) operation
• Features low on-resistance for efficient signal transmission
• Includes break-before-make switching capability to prevent signal overlap

Analog Switches - Special Purpose Applications

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

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'CWN+' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the 18-SOIC package dimensions match the target PCB footprint. Confirm that the operating voltage requirements align with the system design before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring dual 4:1 analog switching with wide voltage tolerance. Compare the 250 Ohm on-resistance against load requirements to ensure signal integrity. Consider the 18-SOIC package size relative to available board space compared to alternative DIP packages like the MAX311CPE+.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX311 series of CMOS RF video multiplexers. It serves as the surface-mount equivalent to through-hole variants such as the MAX311CPE+. The series is designed for general-purpose analog signal switching in video and RF applications.

Analog Switches - Special Purpose Replacement Considerations

The MAX311CPE+ is a direct pin-compatible replacement in a PDIP-16 package. Verify package dimension differences between SOIC and DIP formats during retrofitting.
