MAX4749EUD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4749EUD+ is a low-voltage, quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2V to +11V supply and handles rail-to-rail analog signals. The device features two normally open (NO) switches and two normally closed (NC) switches. Key electrical parameters include an on-resistance of 25Ω max at +5V and 50Ω max at +3V, with matching between channels of 3Ω max at +5V and 3.5Ω max at +3V. Leakage current is guaranteed below 0.1nA at +25°C. Quiescent power consumption is typically less than 0.5nW. The component is housed in a 14-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and RoHS compliance status. Ensure that the procurement channel provides valid traceability for the Analog Devices Inc./Maxim Integrated brand. Cross-reference the part number with the latest datasheet revision to confirm pin configurations and electrical characteristics match the intended application requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4749EUD+ when a mixed configuration of normally open and normally closed analog switches is required within a single package. Consider this component for designs requiring low leakage current and minimal power dissipation. Verify that the system supply voltage falls within the specified +2V to +11V range and that the logic input levels are compatible with the TTL/CMOS standards defined in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4749EUD+ belongs to the MAX4747–MAX4750 family of low-voltage analog switches. This series offers various configurations including quad SPST and dual SPDT options. The EUD+ suffix indicates a lead-free, RoHS-compliant version packaged in a 14-pin Thin Shrink Small Outline Package (TSSOP). The family is designed for portable electronics and communication circuits requiring small form factors and low power operation.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4747EUD+, MAX4748EUD+, and MAX4750EUD+ are part of the same family but differ in switch configuration. The MAX4747EUD+ contains four normally open switches, while the MAX4748EUD+ contains four normally closed switches. The MAX4750EUD+ features two dual single-pole/double-throw switches. Direct pin-for-pin replacement is possible only if the specific NO/NC configuration matches the circuit design requirements.
