MAX399CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX399CSE is a precision, monolithic CMOS analog multiplexer featuring dual 4-channel (2 x 4:1) configuration in a 16-pin Narrow SOIC package. It operates with single +3V to +15V or bipolar ±3V to ±8V supplies. Key electrical parameters include a maximum on-resistance of 225Ω at +3V single supply and 100Ω at ±5V dual supply, with channel matching within 13Ω. The device exhibits low leakage current (<2.5nA at +85°C), charge injection under 5pC, and transition times up to 575ns at +3V. Logic inputs are TTL/CMOS compatible, and the component supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature grade (0°C to +70°C) and Narrow SOIC-16 package format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure logic levels match system requirements for reliable switching operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4-channel multiplexing is required in a compact surface-mount footprint. Consider the higher on-resistance compared to the MAX398 if lower resistance is critical for high-current applications. Verify that the single-supply or dual-supply architecture aligns with the target system power design constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX399CSE belongs to the MAX398/MAX399 family of precision analog multiplexers manufactured by Analog Devices / Maxim Integrated. While the MAX398 provides an 8-channel configuration, the MAX399 offers two independent 4-channel sets, providing flexibility for differential signal routing or isolated channel groups within the same 16-pin form factor.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include DG409, DG509A, and MAX398 (if 8 channels are acceptable). Verify pinout compatibility and electrical parameter tolerances before substitution.
