MAX339ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX339ESE+ 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. Leakage currents are extremely low, with off-leakage less than 20pA at +25°C. The part features TTL-compatible control inputs, guaranteed charge injection of 1.5pC typical, and ESD protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature range and 'SE' indicates the 16-pin Narrow SOIC package. Ensure the '+' suffix denotes lead-free/RoHS compliance as per manufacturer standards. Confirm pinout alignment with legacy DG509A equivalents if used as a drop-in replacement. Validate supply voltage requirements against system constraints before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4-to-1 switching is required within a compact surface-mount footprint. The MAX339ESE+ offers lower leakage compared to standard CMOS switches but higher on-resistance than precision variants like the MAX329. Consider the 400Ω on-resistance impact on signal integrity for high-impedance sources. Verify that the 2-bit address decoding meets the system's control logic availability.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX339ESE+ belongs to the MAX338/MAX339 family of monolithic CMOS analog multiplexers. It serves as a pin-compatible upgrade to industry-standard parts like the DG509A. The 'E' grade provides extended temperature operation compared to the 'C' grade commercial version. The device is fabricated using Maxim’s 44V silicon-gate process for robust performance.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the DG509A. For lower leakage applications, consider the MAX329, though it has higher on-resistance. For higher speed or different channel counts, evaluate the MAX338 (8-channel) or MAX393 (quad SPST). Verify thermal dissipation limits when replacing similar packages.
