MAX4748EBE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4748EBE+T is a low-voltage, quad single-pole double-throw (SPDT) 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 four normally closed (NC) switches with an on-resistance of 50Ω (max) at +3V and 25Ω (max) at +5V. It consumes less than 0.5nW quiescent power and exhibits leakage current below 0.1nA. The component is available in a 16-bump Wafer-Level Package (WLP) measuring 2mm x 2mm.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package type and suffix against official documentation before procurement. Confirm that the ordering suffix corresponds to the desired packaging format, such as tape and reel or tube. Ensure compatibility with RoHS standards if required by the design specifications. Cross-reference the manufacturer's part number with authorized distributors to ensure authenticity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPDT switch with normally closed logic is required. Consider the 50Ω on-resistance limits at +3V and +25Ω at +5V for signal integrity requirements. Evaluate the 2mm x 2mm WLP footprint for space-constrained designs. Verify that the operating temperature range of -40°C to +85°C meets environmental conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4748EBE+T belongs to the MAX4747–MAX4750 family of low-voltage analog switches. This series includes variants with different switch configurations, such as normally open (MAX4747), mixed NO/NC (MAX4749), and dual SPDT (MAX4750). All members share similar electrical characteristics and are designed for portable and battery-operated electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include MAX4747EWE+T (NO), MAX4749EWE+T (Mixed), and MAX4750EWE+T (Dual SPDT). These parts share identical pinouts and electrical parameters but differ in switch state logic.
