MAX4737EBE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4737EBE+T is a quad single-pole/single-throw (SPST) 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 low on-resistance of 4.5Ω maximum at +3V and 3Ω maximum at +5V. The device offers 0.4Ω channel matching and 1.2Ω flatness, with less than 0.5nA leakage current. It supports rail-to-rail signal handling, break-before-make switching, and provides high off-isolation (-55dB at 10MHz). Packaged in a 16-bump UCSP format, it functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status indicated by the plus suffix. Ensure the UCSP package type matches the design footprint requirements. Validate that the specific ordering code corresponds to the intended switch configuration variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and minimal charge injection are critical for maintaining signal fidelity. Verify that the 16-bump UCSP package dimensions fit the available board space. Ensure the control logic voltage levels align with the specified VIH and VIL thresholds for the target supply voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4737/MAX4738/MAX4739 family of low-voltage analog switches. The MAX4737 variant specifically contains four normally open switches. Other family members include the MAX4738 with four normally closed switches and the MAX4739 with a combination of two normally open and two normally closed switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same series include the MAX4738ETE and MAX4739ETE in Thin QFN packages, or the MAX4737EUD in TSSOP. These variants share identical electrical characteristics but differ in physical package geometry and pinout arrangement.
