MAX3408EUK+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX3408EUK+T is a line-terminating network designed to switch between 100 Ω and 120 Ω termination values based on the state of a digital control line. It operates from a +4.5V to +5.5V power supply with a maximum supply current of 50µA. The device guarantees ±2.5% resistance accuracy over an extended temperature range of -40°C to +85°C for signal levels up to ±3.6V. It features a turn-on time and turn-off time of 50 µs, input hysteresis of 200 mV, and accepts bipolar input voltages. The component is housed in a compact 5-pin SOT23 package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Ensure that the procurement channel provides valid traceability for the Analog Devices/Maxim Integrated product line. Cross-reference the part number with the latest datasheet revision to confirm compliance with RoHS standards and other regulatory requirements before finalizing acquisition.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX3408EUK+T when a system requires switching specifically between 100 Ω and 120 Ω termination impedances. This component is suitable for applications needing low standby power and high accuracy over wide temperature variations. Verify that the available supply voltage falls within the specified +4.5V to +5.5V range and that the signal levels do not exceed the ±3.6V limit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX3408EUK+T belongs to the MAX3406/MAX3407/MAX3408 family of general-purpose line-terminating networks. While the MAX3406 switches between 75 Ω and 100 Ω, and the MAX3407 switches between 75 Ω and 120 Ω, the MAX3408 is uniquely configured for 100 Ω to 120 Ω transitions. All devices in this series share the same 5-pin SOT23 package and electrical characteristics regarding power consumption and operating voltage.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX3406EUK+T and MAX3407EUK+T are related components within the same family but offer different termination combinations. Direct substitution is only viable if the circuit design accommodates the alternative impedance values provided by these variants.
