MAX339MSE/PR3+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX339MSE/PR3+T is a dual, 4-channel CMOS analog multiplexer designed for military and industrial applications. It operates from single +4.5V to +30V or dual ±4.5V to ±20V supplies. The device features a maximum on-resistance of 400Ω at +25°C and 500Ω across the full temperature range. Off-leakage current is guaranteed to be less than 20pA at +25°C and within ±20nA over the extended temperature range. Charge injection is typically 1.5pC. The component utilizes a 16-pin Narrow SO package and supports an operating temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix /PR3 corresponds to the specific reel packaging configuration required for automated assembly processes. Confirm that the lead-free designation aligns with environmental compliance standards mandated by the target market. Ensure the military temperature grade matches the operational requirements of the final deployment environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low leakage and high voltage tolerance are critical. The dual 4-channel architecture allows independent routing of two separate signal groups. Verify that the 400Ω on-resistance meets the signal integrity requirements of the application. Consider the 16-pin narrow SO footprint constraints during PCB layout planning.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX338/MAX339 family of monolithic CMOS analog multiplexers. It serves as a pin-compatible upgrade for industry-standard DG509A devices. The MAX339 variant specifically provides dual 4-channel switching capabilities, distinguishing it from the single 8-channel MAX338 counterpart.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance specified for the MAX339MSE/PR3+T?

The maximum on-resistance is 400Ω at +25°C and increases to 500Ω across the full operating temperature range.

How does the MAX339 handle overvoltage conditions on input pins?

Signals on NO, COM, EN, A0, A1, or A2 exceeding V+ or V- are clamped by internal diodes. Forward current must be limited to the maximum ratings.

Is the MAX339MSE/PR3+T compatible with TTL logic levels?

Yes, all control inputs are TTL compatible (+0.8V to +2.4V) over the full specified temperature range and supply voltage range.
