MAX396EWI+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX396EWI+T is a precision, low-voltage CMOS analog multiplexer featuring 16 single-ended channels in a 28-pin Wide SOIC package. It operates with a single supply from +2.7V to +16V or dual supplies of ±2.7V to ±8V. Key electrical parameters include a maximum on-resistance of 100Ω at ±5V and 550Ω at +3V single supply, with guaranteed matching within 6Ω and flatness within 10Ω. The device exhibits low off-leakage current (<1nA at +85°C), charge injection of 5pC max, and transition times under 250ns. Logic inputs are TTL/CMOS compatible, and the component supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the suffix 'EWI' corresponds to the Wide SOIC-28 package and the '+T' indicates tape-and-reel packaging. Confirm the 'E' grade matches the required -40°C to +85°C industrial temperature range. Ensure the datasheet revision aligns with design specifications before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high channel count and precise signal routing in low-voltage environments. Consider the 100Ω on-resistance limit when designing for minimal signal attenuation. Verify logic voltage compatibility, as the device requires specific thresholds for reliable switching across the full supply range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX396/MAX397 family of precision analog multiplexers. The MAX396 variant provides 16 single-ended channels, whereas the MAX397 offers dual 8-channel configurations.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX396 handle power-supply sequencing?

Proper sequencing is recommended: apply V+ first, then V-, followed by logic inputs and analog signals. If sequencing cannot be controlled, external blocking diodes should be added to prevent damage.

What is the behavior if supply voltages drop below 2.7V?

Performance is not guaranteed below 2.7V. While the switch state may remain proper during slow ramp-up or down, on-resistance and switching times become excessively high.

Is the MAX396 compatible with TTL logic levels?

Yes, the device features TTL/CMOS compatible logic inputs, allowing direct interfacing with standard digital control circuits without additional level shifting.
