MAX337EAI+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX337EAI+T is a monolithic CMOS analog multiplexer featuring two independent 8-channel switches in a 28-pin SSOP package. It connects one of eight inputs to a common output via a 3-bit binary address. The device operates from single +4.5V to +30V or dual ±4.5V to ±20V supplies. Key electrical parameters include a maximum on-resistance of 700Ω (single supply) or 500Ω (dual supply), off-leakage current less than 1.25nA at -40°C to +85°C, and typical charge injection of 3.5pC. Transition time is 600ns (single supply) or 500ns (dual supply). Control inputs are TTL compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the 'E' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the ordering part number matches the required 28-pin SSOP package configuration for your PCB layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX337EAI+T when dual 8-channel multiplexing is required within a compact surface-mount footprint. This model is suitable for applications demanding low leakage and high ESD robustness. Verify that the system voltage requirements fall within the specified single or dual supply ranges to ensure proper logic compatibility and signal handling.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX336/MAX337 family of low-leakage CMOS analog multiplexers. It serves as a pin-compatible upgrade for industry-standard DG506 and DG507 devices. The MAX337 variant specifically provides dual 8-channel functionality, whereas the MAX336 offers a single 16-channel configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX337EAI+ is functionally equivalent to the non-suffix version. For alternative packages, consider the MAX337EWI+ (Wide SO) or MAX337EPI+ (Plastic DIP). Verify thermal derating requirements if replacing with different package types.
