MAX339ETE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX339ETE+T is a dual, 4-channel CMOS analog multiplexer designed to connect one of four inputs to a common output via a 2-bit binary address. 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 extremely low off-leakage currents below 20pA. It provides over 2000V ESD protection per method 3015.7 and includes TTL-compatible control inputs. Packaged in a 16-pin TQFN-EP (5mm x 5mm) with an exposed pad connected to V+, it supports bidirectional signal flow.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual 4-channel architecture allowing independent routing of two sets of four inputs to separate outputs.
• Extremely low leakage characteristics with off-leakage under 20pA and on-channel leakage under 50pA.
• Robust electrostatic discharge protection exceeding 2000V using method 3015.7.
• TTL-compatible logic inputs ensuring compatibility across specified temperature and supply ranges.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data-acquisition systems
• Test equipment
• Military radios
• Guidance and control systems
• Sample-and-hold circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'ETE+' corresponds to the 16-pin TQFN-EP package with lead-free compliance. Confirm that the exposed pad connection requirements align with your PCB thermal design. Ensure the ordering documentation matches the Analog Devices/Maxim Integrated specifications for the -40°C to +85°C industrial temperature range.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-channel configuration is required instead of an 8-channel solution. Consider the 400Ω on-resistance limit if signal integrity at higher voltages is critical. Verify that the 500ns transition time meets system timing constraints. This part serves as a pin-compatible upgrade for industry-standard DG509A devices.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX338/MAX339 family of monolithic CMOS analog multiplexers. While the MAX338 provides a single 8-channel configuration, the MAX339 offers dual 4-channel functionality within the same footprint. Both share identical electrical characteristics regarding resistance and leakage, differing only in channel count and address decoding logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX339ETE+T is a direct pin-compatible replacement for the DG509A. For applications requiring lower leakage but accepting higher on-resistance, the MAX329 may be considered.
