MAX4747ETE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4747ETE+T is a low-voltage, quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single +2V to +11V supply and handles rail-to-rail analog signals. The device features 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. Quiescent power consumption is typically less than 0.5nW, and leakage current is guaranteed below 0.1nA at +25°C. It utilizes a 16-pin Thin QFN package with an exposed pad.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required package type and temperature range. Ensure compliance with RoHS standards as indicated by the plus sign in the part number. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring low voltage operation between +2V and +11V. The 16-pin Thin QFN package is appropriate for space-constrained PCB layouts. Consider the on-resistance flatness and matching requirements relative to the specific supply voltage used in the application. Ensure that the logic input levels are driven rail-to-rail to minimize power consumption and maintain TTL compatibility at lower supply voltages.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4747ETE+T belongs to the MAX4747–MAX4750 family of low-voltage analog switches. This series includes variations such as the MAX4748 (quad NC), MAX4749 (mixed NO/NC), and MAX4750 (dual SPDT). All members share similar electrical characteristics and packaging options, including TSSOP, Thin QFN, and WLP packages, allowing for flexible design integration within the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Compatible substitutes within the same family include the MAX4748ETE+T, MAX4749ETE+T, and MAX4750ETE+T. These parts share identical pinouts and electrical specifications but differ in internal switch configuration (normally closed, mixed, or SPDT). Verify that the specific switch topology meets the circuit requirements before substituting.
