MAX4645EUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4645EUK-T is a single-pole, single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a +1.8V to +5.5V single supply and features a typical on-resistance of 2.5Ω at +5V. The device handles Rail-to-Rail analog signals with off-leakage current limited to 0.25nA maximum at +25°C. It offers fast switching speeds, including a 12ns turn-on time and an 8ns turn-off time. The component is housed in a 5-pin SOT-23 package and supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EUK+T' against official manufacturer documentation to confirm the exact package type and temperature grade. Ensure that the procurement channel provides genuine components with traceable origin. Cross-reference the part number with the latest datasheet revision to validate pin configurations and electrical specifications before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring low on-resistance and fast switching within a compact footprint. Consider the 5-pin SOT-23 package constraints regarding power dissipation and thermal management. Evaluate the voltage compatibility between the control logic and the analog signal range to ensure proper operation across the full temperature spectrum.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4645/MAX4646 family of fast, low-voltage analog switches. The MAX4645 variant specifically functions as a normally open switch, distinguishing it from the normally closed MAX4646 model. Both share identical electrical characteristics and packaging options, facilitating design flexibility for SPST switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same series include the MAX4646EUK-T, which offers the same specifications but with a normally closed configuration.
