MAX4684EBC+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4684EBC+T is a dual single-pole/double-throw (SPDT) 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, with the NC switch at 0.5Ω max and the NO switch at 0.8Ω max at a +2.7V supply. The device offers break-before-make switching action with tON = 50ns and tOFF = 40ns at +3V. Digital logic inputs are 1.8V compatible. It is packaged in a 12-bump UCSP measuring 2.0mm x 1.50mm.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Ensure that the procurement channel provides valid traceability for the component. Confirm that the received part matches the specified electrical characteristics and packaging details before integration into the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPDT switch with low on-resistance and small footprint is required. Consider the asymmetrical Ron values if different load requirements exist for normally closed and normally open paths. Verify that the operating voltage range aligns with the system's power supply constraints and that the UCSP package assembly methods meet reliability standards.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4684EBC+T belongs to the MAX4684/MAX4685 family of low-voltage, dual SPDT analog switches. This series is designed for applications requiring minimal board space and efficient power consumption. The EBC suffix specifically denotes the 12-bump UCSP package variant within the product line.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4684 and MAX4685?

The MAX4684 features an asymmetrical on-resistance with 0.5Ω max for the NC switch and 0.8Ω max for the NO switch at +2.7V. The MAX4685 has a symmetrical 0.8Ω max on-resistance for both NO and NC switches.

How does the UCSP package affect mechanical reliability?

The UCSP package relies on direct solder contact to the PCB, lacking the stress relief of traditional lead frames. Mechanical stress performance depends heavily on user assembly methods, circuit board material, and usage environment.

Can the digital logic inputs handle voltages higher than the supply voltage?

Yes, the logic inputs accept up to +5.5V regardless of the supply voltage. For example, with a +3.3V supply, IN_ can be driven high to 5.5V.
