MAX4646EUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4646EUK-T is a single-pole, single-throw (SPST) 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 an off-leakage current of 0.25nA maximum at +25°C. It offers fast switching speeds, including a turn-on time of 12ns and a turn-off time of 8ns. The component is housed in a 5-pin SOT-23 package and functions as a normally closed switch.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type and temperature range. Confirm RoHS compliance status through the manufacturer's datasheet or authorized distributor channels before procurement. Ensure that the supply voltage and logic levels match the system requirements to prevent damage.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed SPST configuration is required within a low-voltage environment. Consider the 2.5Ω on-resistance and 12ns turn-on time for applications demanding fast signal switching. Evaluate the -40°C to +85°C operating temperature range against environmental conditions. Compare power consumption and leakage specifications against alternative switches for optimal efficiency.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4645/MAX4646 family of fast, low-voltage analog switches. The MAX4646 variant specifically provides a normally closed contact state, distinguishing it from the normally open MAX4645. Both share identical electrical characteristics and packaging options, allowing for design flexibility based on default switch states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4645 serves as a functional substitute if a normally open switch configuration is acceptable. Verify pin compatibility and electrical parameters such as on-resistance and switching times when considering cross-references within the same product family.
