MAX336EWI+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX336EWI+T is a monolithic CMOS analog multiplexer featuring 16 channels. 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 of 400Ω (max) at +25°C, rising to 500Ω across the temperature range. Off-leakage current is less than 20pA at +25°C and 1.25nA at maximum temperature. Transition time is typically 500ns, with enable turn-on/off times up to 750ns. Charge injection is typically 3.5pC. It provides over 2000V ESD protection per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging requirements. Ensure the Wide SO package code matches the target PCB footprint. Confirm RoHS compliance status for environmental regulations. Validate that the -40°C to +85°C industrial temperature grade meets operational needs. Cross-reference the manufacturer part number to avoid counterfeit components.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a 16-channel analog switch is required with low leakage characteristics. Consider the Wide SO-28 package for surface-mount assembly constraints. Evaluate supply voltage ranges to ensure compatibility with single or dual power rails. Check on-resistance specifications against load requirements to minimize signal attenuation. Verify TTL logic compatibility for direct microcontroller interfacing without level shifting.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX336/MAX337 family of CMOS analog multiplexers. It serves as a pin-compatible upgrade for industry-standard DG506 devices. The MAX336 variant specifically handles 16 channels, whereas the MAX337 offers dual 8-channel configurations. Both share similar low-leakage and low-charge-injection architectures designed for high-performance analog signal switching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX336EWI+ is a direct pin-compatible replacement for the DG506. Designers upgrading from legacy parts should verify that the improved leakage and charge injection specs meet system tolerances. No functional changes are expected due to pin compatibility, but thermal derating curves may differ slightly between manufacturers.
