Analog Switches, Multiplexers, Demultiplexers datasheet and documents for MAX4739EUD+

MAX4739EUD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4739EUD+ is a quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. 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 includes two normally open switches and two normally closed switches, offering rail-to-rail signal handling and CMOS logic compatibility. Key electrical parameters include a turn-on time of 80ns maximum, off-isolation of -55dB at 10MHz, and a total harmonic distortion of 0.03%. It functions within an operating temperature range of -40°C to +85°C and is housed in a 14-pin TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status indicated by the plus suffix. Ensure the ordering suffix matches the required package type and temperature grade before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring mixed normally open and normally closed analog switching paths. Verify that the system logic levels align with the specified input thresholds for the chosen supply voltage. Consider thermal dissipation requirements if operating near maximum power limits in enclosed environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4737/MAX4738/MAX4739 family of low-voltage analog switches. While sharing identical electrical performance and pinouts, the MAX4739 is distinguished by its specific combination of two normally open and two normally closed channels, unlike the all-open MAX4737 or all-closed MAX4738 variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4737EUD+ and MAX4738EUD+. These parts share identical pin configurations and electrical specifications but differ in internal switch configuration. Verify that the specific NO/NC channel arrangement meets the circuit design requirements before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4739 and the MAX4737?

The MAX4739 contains two normally open and two normally closed switches, whereas the MAX4737 contains four normally open switches. Both share the same electrical characteristics and pinout.

Does the MAX4739 support break-before-make switching?

Yes, the MAX4739 specifically features break-before-make switching with a delay of approximately 8ns typical, which prevents signal shorting during transitions.
