MAX339CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX339CSE+ is a dual, 4-channel CMOS analog multiplexer in a 16-pin Narrow SO package. It connects one of four inputs to a common output via a 2-bit binary address. The device operates from single +4.5V to +30V or dual ±4.5V to ±20V supplies. Key electrical parameters include a maximum on-resistance of 400Ω at +25°C and 500Ω across the full temperature range. Off-leakage current is less than 20pA at +25°C, with typical charge injection of 1.5pC. Control inputs are TTL compatible (+0.8V to +2.4V). The component supports bidirectional signal flow and features ESD protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' corresponds to the commercial temperature range (-40°C to +85°C is not applicable; C denotes 0°C to +70°C) and the narrow SOIC-16 package. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the source document matches the official Analog Devices datasheet for accurate pinout and absolute maximum ratings before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a dual 4:1 multiplexer configuration is required within a standard 16-pin surface-mount footprint. It serves as a pin-compatible upgrade for industry-standard DG509A devices. Consider the MAX338 if an 8-channel single-ended mux is needed instead. Evaluate the 400Ω on-resistance against system requirements, noting that lower resistance alternatives exist but may have different leakage characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX338/MAX339 family of monolithic CMOS analog multiplexers manufactured by Analog Devices/Maxim Integrated. The MAX339 specifically provides two independent 4-to-1 channels. The family is characterized by low leakage and robust ESD protection, designed for precision analog signal routing in industrial and military environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX339CSE+ is a direct pin-compatible replacement for the DG509A. For similar functionality with lower leakage but higher on-resistance, consider the MAX329.
