MAX4750EUD+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4750EUD+T is a low-voltage analog switch IC featuring two single-pole double-throw (SPDT) channels in a 14-pin TSSOP package. It operates from a single +2V to +11V supply and handles rail-to-rail analog signals. Key electrical parameters include a maximum on-resistance of 50Ω at +3V and 25Ω at +5V, with channel matching of 3.5Ω max at +3V and 3Ω max at +5V. Leakage current is guaranteed below 0.1nA at +25°C. The device consumes less than 0.5nW quiescent power, features TTL/CMOS logic compatibility, and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the '+T' designation aligns with lead-free and RoHS compliance requirements for your manufacturing process. Ensure the 14-pin TSSOP footprint matches your PCB layout specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4750EUD+T when dual SPDT switching functionality is required within a compact surface-mount package. This part is suitable for designs needing rail-to-rail signal transmission with low distortion. Consider the 50Ω on-resistance limits when designing for high-current paths or strict voltage drop constraints in low-voltage applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4747–MAX4750 family of low-voltage analog switches manufactured by Analog Devices / Maxim Integrated. While other members of the series offer quad SPST configurations or different terminal states, the MAX4750 specifically provides two SPDT switches. It shares the same core CMOS technology and low-power characteristics as its siblings but differs in internal topology and pin assignments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same family include the MAX4747, MAX4748, and MAX4749, though these feature different switch configurations such as quad SPST or mixed NO/NC terminals. Verify pin compatibility and logical state inversion differences when substituting these parts in existing designs.

Analog Switches, Multiplexers, Demultiplexers FAQ
