MAX4639EGE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4639EGE+T is a dual, low-voltage CMOS analog switch manufactured by Analog Devices Inc. (Maxim Integrated). It integrates two independent 4:1 multiplexers within a single 16-pin QFN-EP package. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V or dual supplies up to ±2.75 V. Key electrical specifications include a maximum on-resistance of 3.5 Ohms, an 85 MHz -3dB bandwidth, and a propagation delay of 18 ns. The component supports a continuous current of 75 mA and features low charge injection of 13 pC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different packaging or temperature grades. Confirm RoHS compliance status through manufacturer certificates. Ensure the supplier provides traceable origin data to mitigate counterfeit risks. Cross-reference the part number with the latest datasheet revision to validate pinout and electrical characteristics before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4:1 mux functionality is required in a compact footprint. The 3.5 Ohm on-resistance suits applications demanding low insertion loss. Verify that the 1.8 V minimum supply meets system requirements. Consider the QFN-EP package for thermal performance and PCB space constraints compared to larger packages.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4638/MAX4639 family of low-voltage analog switches. It shares architectural similarities with the MAX4638 but offers dual 4:1 configuration instead of single 8:1. The series is designed for battery-powered and low-voltage digital systems requiring high-speed analog signal switching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4638ETE+T is a related single-channel variant. Direct functional substitutes require matching the 3.5 Ohm Ron, 85 MHz bandwidth, and 16-pin QFN-EP package. Verify pin compatibility and electrical limits before substitution.
