MAX397CAI

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX397CAI is a precision, low-voltage CMOS analog multiplexer featuring two independent 8-channel switches in a 28-pin SSOP package. It operates with single supplies from +2.7V to +16V or dual supplies from ±2.7V to ±8V. Key electrical specifications 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 exhibits fast switching speeds, with transition times under 250ns and charge injection limited to 5pC. Input off-leakage current remains below 1nA at +85°C, ensuring high signal integrity.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Low on-resistance with tight matching and flatness guarantees over signal ranges
• TTL/CMOS compatible logic inputs for direct interfacing with digital control systems
• High electrostatic discharge protection exceeding 2000V per Method 3015.7

Analog Switches, Multiplexers, Demultiplexers Applications

• Automatic test equipment signal routing
• Audio signal routing and switching matrices
• Industrial process control data acquisition
• Sample-and-hold circuits
• Avionics systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CAI confirms the commercial temperature range (0°C to +70°C) and SSOP-28 packaging. Confirm RoHS compliance status if required by assembly standards. Ensure supply voltage sequencing adheres to absolute maximum ratings to prevent latch-up or damage during power-up cycles.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 8-channel switching is required rather than a single 16-channel path. Verify that the 100Ω on-resistance meets the load requirements compared to lower resistance alternatives. Ensure the operating environment stays within the commercial temperature limits; otherwise, consider the E or M grade variants for extended or military ranges.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX396/MAX397 family of low-voltage CMOS analog multiplexers. It serves as the dual-channel counterpart to the MAX396, which offers a single 16-channel configuration. Both devices share pin compatibility with industry-standard parts like the MAX306/MAX307 and DG406/DG407, facilitating drop-in replacements in existing designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible substitutes include the MAX307, DG407, and DG507A. Verify that replacement parts meet the specific 100Ω on-resistance and 5pC charge injection requirements to maintain circuit performance.
