MAX4651ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4651ESE+T is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single +1.8V to +5.5V supply and features four normally closed switches in the SOIC-Narrow-16 package. Key electrical parameters include a maximum on-resistance of 4Ω at +5V, an on-resistance matching of 0.2Ω max, and off-leakage current of 0.1nA at +25°C. The device supports rail-to-rail analog signals, with turn-on time typically 20ns and turn-off time typically 12ns.

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 directives as indicated in the product documentation before integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high channel matching are critical for signal integrity. The single-supply operation simplifies power design compared to dual-supply alternatives. Consider the thermal dissipation capabilities of the SOIC package if operating near maximum ratings.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4651/MAX4652/MAX4653 family of low-voltage analog switches. While the MAX4651 offers four normally closed switches, the MAX4652 provides four normally open switches, and the MAX4653 combines two of each. All variants share similar electrical characteristics and pin configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4652ESE+T and MAX4653ESE+T, which offer different switch states but identical electrical performance. Cross-family replacements may require verification of on-resistance and supply voltage compatibility.
