MAX399ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX399ESE+T is a precision, monolithic CMOS analog multiplexer featuring two independent 4-channel (SP4T) switches in a 16-pin Narrow SOIC package. It operates with single +3V to +15V or bipolar ±3V to ±8V supplies. Key electrical parameters include an on-resistance of 100 Ω maximum at ±5V dual supply and 225 Ω maximum at +5V single supply. The device guarantees channel-to-channel on-resistance matching within 6 Ω and offers low off-leakage current of less than 2.5 nA at +85°C. Switching speeds feature a transition time of 250 ns maximum and charge injection below 5 pC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the industrial temperature range of -40°C to +85°C and 'S' denotes the Narrow SOIC package. Confirm the '+' suffix ensures compliance with RoHS standards. Cross-reference the datasheet revision history to ensure the document matches the manufacturing date code for any pinout or specification updates.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4-channel switching is required in a narrow surface-mount footprint. Ensure the application signal range fits within the specified supply voltages, as lower supplies reduce the linear signal window. Verify that the 100 Ω on-resistance meets the system's voltage drop requirements compared to lower-resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX398/MAX399 family of precision analog multiplexers. While the MAX398 provides eight channels in a single package, the MAX399 splits the functionality into two isolated 4-channel blocks. Both share identical fabrication processes and electrical characteristics, differing primarily in channel count and address pin configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include DG409, DG509A, and MAX398 (if 8 channels are acceptable). Verify pin compatibility and on-resistance specifications before substitution.
