MAX397C/D

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX397C/D is a dual, 8-channel low-voltage CMOS analog multiplexer. It operates with single supplies from +2.7V to +16V or dual supplies of ±2.7V to ±8V. The device features a maximum on-resistance of 100Ω at +25°C and guarantees channel-to-channel matching within 6Ω. It provides fast switching speeds with transition times under 250ns and extremely low charge injection of 5pC maximum. Input off-leakage current remains below 1nA at +85°C. The C/D suffix indicates the component is available as silicon dice for temperatures ranging from 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package type required for the application, as the MAX397C/D designation refers specifically to bare silicon dice. Ensure that the manufacturing facility has the necessary capabilities for die attachment and packaging if procuring this form factor. Confirm temperature range compliance with the C suffix (0°C to +70°C) against system requirements before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX397 over the MAX396 when a dual 8-channel configuration is preferred over a single 16-channel layout. Consider the E suffix (-40°C to +85°C) or M suffix (-55°C to +125°C) if operation outside the commercial temperature range is required. Verify that the 100Ω on-resistance meets the signal integrity requirements of the target circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX397 belongs to the Maxim Integrated low-voltage CMOS analog switch family. It serves as a pin-compatible replacement for industry-standard parts like the DG407 and MAX307. This series is designed for precision applications requiring low distortion and high isolation in compact footprints.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX397 is pin-compatible with the DG407, MAX307, and DG507A. When substituting these devices, verify that the alternative's on-resistance flatness and leakage specifications meet the original design constraints.
