MAX4676EUT-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4676EUT-T is a single-channel, normally-closed SPST analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.7V to 5.5V or dual supplies of ±2.7V to ±5.5V. The device features a maximum on-resistance of 3 Ohms and a -3dB bandwidth of 250MHz. Switching times are specified with a maximum turn-on time of 300ns and turn-off time of 110ns. Charge injection is 87pC, while off-state leakage current is limited to 1nA. It is housed in an SOT-23-6 package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official documentation, as variations may exist between tape-and-reel and cut-tape packaging formats. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as environmental certifications can vary by production batch and region. Ensure the component source is traceable to Analog Devices Inc. or Maxim Integrated to avoid counterfeit parts.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed state is required upon power loss or control signal absence. Compare the 3 Ohm on-resistance against system impedance requirements to ensure signal integrity. Evaluate the 250MHz bandwidth against the highest frequency component in the signal chain. Consider the SOT-23-6 package size constraints relative to available PCB real estate.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4675-MAX4677 family of high-speed, low-power CMOS analog switches. These devices share similar electrical characteristics but differ in configuration, such as normally-open versus normally-closed states. The MAX4676 specifically provides the normally-closed variant within this series, offering consistent performance metrics across the family while differing in default signal path behavior.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4675 (normally-open) if the logic state difference is acceptable. Other single-channel SPST switches from Analog Devices should be evaluated for pin compatibility and electrical parameter alignment before substitution.
