MAX4656EUA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4656EUA+T is a single-pole/single-throw (SPST) CMOS analog switch designed for medium-voltage applications. It features a maximum on-resistance of 10Ω and supports continuous switch currents up to 300mA with peak capabilities of 400mA. The device operates within a supply range of ±4.5V to ±20V for dual supplies or +9V to +40V for single-supply configurations, accommodating rail-to-rail analog signals. Key electrical parameters include a typical turn-on time of 110ns and turn-off time of 75ns at ±15V supplies. It offers low off-leakage current (1nA max), high off-isolation (-77dB at 1MHz), and a -3dB bandwidth of 210MHz. The component is housed in an 8-pin µMAX package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. Ensure the supplier provides documentation confirming RoHS compliance and lead-free status. Cross-reference the manufacturer part number with official datasheets to validate authenticity and revision history before integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high continuous current switching is required alongside low on-resistance. Verify that the application voltage stays within the specified single or dual supply limits. Consider the thermal dissipation capabilities of the µMAX package if operating near maximum current ratings. Ensure logic levels match the TTL/CMOS input requirements for reliable switching control.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4655–MAX4658 family of high-current CMOS analog switches. While pin-compatible with older discrete gate equivalents like the DG417/DG418, it offers superior performance in terms of current handling and switching speed. The MAX4656 variant specifically provides a normally open configuration, distinguishing it from the normally closed MAX4655.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4656EUA+T is pin-compatible with the DG417 and DG418. Designers replacing these legacy parts should verify that the new switch's current and voltage ratings meet the original circuit demands.
