MAX336EWI

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX336EWI+ is a monolithic CMOS analog multiplexer featuring 16 channels in a 28-pin Wide SO package. It connects one of 16 inputs to a common output via a 4-bit binary address. The device operates from single +4.5V to +30V or dual ±4.5V to ±20V supplies. Key electrical parameters include an on-resistance maximum of 700Ω (single supply) or 500Ω (dual supply), off-leakage current less than 20pA at +25°C, and charge injection typically 3.5pC. It provides over 2000V ESD protection per method 3015.7 and functions as both a multiplexer and demultiplexer.

• TTL-compatible control inputs across the full specified temperature range
• Bidirectional signal conduction with pin-compatible design for legacy upgrades

Analog Switches, Multiplexers, Demultiplexers Applications

• Precision data acquisition systems
• Precision signal routing networks
• Test and measurement equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWI+' corresponds to the required Wide SO package and -40°C to +85°C operating temperature range. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure logic voltage levels match TTL compatibility requirements for the intended application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a 16-channel configuration is required rather than the dual 8-channel MAX337. Consider the Wide SO package dimensions against available board space. Evaluate single-supply versus dual-supply operation needs, as on-resistance and transition times vary significantly between the two power configurations.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX336/MAX337 family of low-leakage CMOS analog multiplexers. It serves as a direct upgrade replacement for industry-standard DG506 and DG507 devices while maintaining pin compatibility. The series offers improved performance characteristics including lower charge injection and higher ESD tolerance compared to previous generations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX336EWI+ is functionally compatible with the DG506 and DG507. Verify that the legacy components' absolute maximum ratings are not exceeded during the transition. Check if the original design requires specific break-before-make timing characteristics that differ between the older silicon and the Maxim Integrated version.
