MAX339MSE/PR3+ is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC SW SP4T-NO/NCX2 400OHM 16SOIC. Review the specifications below when checking this part for your BOM.
The MAX339MSE/PR3+ is a dual, 4-channel CMOS analog multiplexer designed for military and aerospace applications. It connects one of four inputs to a common output via a 2-bit binary address. The device operates from single supplies of +4.5V to +30V or dual supplies of ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 400Ω at +25°C (rising to 500Ω across the full temperature range) and extremely low off-leakage currents below 20pA at +25°C. Charge injection is typically 1.5pC. The component features TTL-compatible control inputs and provides ESD protection exceeding 2000V per method 3015.7.
Verify the specific suffix /PR3+ against official documentation to confirm package type and lead finish specifications. Ensure the operating environment falls within the -55°C to +125°C range defined for this variant. Cross-reference the manufacturer's current production status as availability may vary for specialized military-grade components.
Select this component when high-temperature operation up to +125°C is required alongside low leakage performance. Compare on-resistance values against system requirements, noting that resistance increases at lower supply voltages. Verify that the 400Ω maximum on-resistance meets the voltage drop constraints of the application circuit.
This part belongs to the MAX338/MAX339 family of monolithic CMOS analog multiplexers. The MAX339 specifically offers a dual 4-channel configuration, whereas the MAX338 provides an 8-channel single-ended setup. Both devices serve as pin-compatible upgrades for industry-standard DG508A and DG509A switches.
