MAX397EWI+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX397EWI+T is a dual, 8-channel low-voltage CMOS analog multiplexer manufactured by Maxim Integrated. It operates with single supplies from +2.7V to +16V or dual supplies from ±2.7V to ±8V. The device features a maximum on-resistance of 100Ω at +25°C and ±5V supplies, with guaranteed matching within 6Ω between channels. Input off-leakage current remains below 1nA at +85°C. Transition times are less than 250ns across the specified temperature range. The component is housed in a 28-pin Wide SO package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix '+T' against the manufacturer's documentation to confirm tape-and-reel packaging requirements. Ensure the ordering code matches the exact temperature grade and package style required for the design. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring dual independent 8-channel switching capabilities. It is suitable for applications demanding low voltage operation down to 2.7V while maintaining high isolation and low leakage characteristics. Consider the 28-pin Wide SO package constraints during PCB layout planning to ensure adequate clearance and thermal management.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX396/MAX397 family of precision analog multiplexers. While the MAX396 provides a single 16-channel configuration, the MAX397 offers a dual 8-channel topology. Both share identical pinouts and electrical specifications, allowing for flexible system design based on channel count requirements without altering the physical footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet confirms pin compatibility with the MAX307, DG407, and DG507A. Verify that substitute components meet the same supply voltage ranges and on-resistance specifications to ensure seamless integration into existing designs without circuit modification.
