MAX397CPI+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX397CPI+ is a dual, 8-channel low-voltage CMOS analog multiplexer housed in a 28-pin Plastic DIP package. It operates with single supplies from +2.7V to +15V or dual supplies from ±2.7V to ±8V. Key electrical parameters include a maximum on-resistance of 100Ω at +25°C and 125Ω across the full temperature range, with channel-to-channel matching guaranteed within 6Ω. The device features a maximum transition time of 250ns, charge injection of 5pC, and off-leakage current below 1nA at +85°C. Logic inputs are TTL/CMOS compatible, requiring 2.4V for high and 0.8V for low states.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'I' confirms the industrial temperature range of 0°C to +70°C and the 'P' indicates the 28-lead plastic DIP package. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with legacy MAX306/MAX307 or DG406/DG407 families is required. Ensure the application voltage does not exceed the absolute maximum ratings of ±17V between supply pins. Verify that the required switching speed and leakage characteristics align with the specified limits for the target operating temperature.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX396/MAX397 family of precision, low-voltage analog multiplexers manufactured by Analog Devices (Maxim Integrated). The MAX397 specifically provides two independent 8-channel switches, whereas the MAX396 offers a single 16-channel configuration. Both share identical logic control interfaces and physical pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include MAX307, DG407, and DG507A due to direct pin compatibility. Verify that replacement parts meet the specific on-resistance and leakage requirements of the original design.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic input voltage threshold for the MAX397?

The logic high input voltage (VAH) must be at least 2.4V, and the logic low input voltage (VAL) must be no more than 0.8V.

How does the on-resistance vary with temperature?

The on-resistance increases with temperature; it is guaranteed to be a maximum of 100Ω at +25°C and up to 125Ω across the full operating temperature range.
