MAX4644EUT-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4644EUT-T is a single-pole/double-throw (SPDT) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply voltage ranging from +1.8V to +5.5V, supporting rail-to-rail analog signal ranges. The device features a maximum on-resistance of 4Ω at +5V and 8Ω at +3V, with typical on-resistance flatness of 0.75Ω. Switching times are typically 18ns for turn-on and 12ns for turn-off, ensuring break-before-make operation. Quiescent power consumption is extremely low, typically 0.01μW. Leakage current is less than 0.35nA across the entire temperature range. The component is housed in a SOT-23-6 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as '+T' variants often denote lead-free and halogen-free construction. Check for obsolescence notices or lifecycle status updates from Analog Devices. Ensure the supplier provides valid traceability documentation for the Maxim Integrated brand history under Analog Devices.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage operation and high-speed switching within a compact SOT-23 footprint. Compare on-resistance specifications against load requirements to ensure signal fidelity. Consider the break-before-make characteristic for preventing short circuits in multiplexed paths. Evaluate leakage current limits against sensitive input stages in data acquisition chains.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4644 belongs to the Maxim Integrated family of high-speed, low-voltage analog switches. It is designed for portable and battery-powered applications where power efficiency and small form factor are critical. The SPDT configuration allows for flexible signal path selection between two sources or destinations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4644EUA+ offers identical electrical performance in an 8-pin uMAX/uSOP package. MAX4644EUT+ provides the same functionality in a standard SOT-23-6 package without the reel-specific suffix. Verify pinout compatibility and thermal characteristics when substituting packages.
