MAX4620EUD+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4620EUD+T is a quad, single-pole/single-throw (SPST) CMOS analog switch in a 14-pin TSSOP package. It operates from a +2V to +12V single supply and features ±15kV ESD protection on NO/NC pins. Key electrical parameters include a maximum on-resistance of 70Ω at 5V and 120Ω at 3V, with typical matching of 0.5Ω and flatness of 2Ω at 5V. The device handles rail-to-rail signals, offers a -3dB bandwidth exceeding 300MHz, and draws only 10µA supply current.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm the 'E' suffix corresponds to the industrial temperature range of -40°C to +85°C. Ensure the '+'' denotes lead-free compliance. Cross-reference the manufacturer's latest datasheet to confirm availability status and any potential obsolescence notices before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4620EUD+T when four independent SPST switches are required in a compact surface-mount package. This part is suitable for applications needing low distortion and high bandwidth. Verify that the system supply voltage falls within the +2V to +12V range. Consider the 70Ω maximum on-resistance limits for current switching requirements compared to lower resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4620/MAX4630/MAX4640 family of low-voltage, high-ESD-protected analog switches. While the MAX4620 contains four normally open switches, the MAX4630 provides four normally closed switches, and the MAX4640 combines two of each. All variants share identical pinouts and electrical characteristics except for the internal switch configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4620 serves as a direct pin-compatible replacement for the 74HC4066, MAX4066, and MAX4610/MAX4611/MAX4612 analog switches. Designers should verify that the replacement meets specific ESD protection requirements, as legacy parts may lack the ±15kV protection found in the MAX4620.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4620 handle ESD events on the signal pins?

The device includes bidirectional SCRs on-chip between the NC/NO terminals and ground. These turn on in nanoseconds to bypass surge currents safely to ground, providing ±15kV Human Body Model and IEC 1000-4-2 protection.

What is the holding current requirement for the ESD SCR?

The SCR holding current is typically 110mA at room temperature and drops to approximately 70mA at +85°C. Sources connected to NC/NO terminals must be current-limited below these values to ensure the SCR turns off after an ESD event.

Can the MAX4620 operate with dual supplies?

No, the MAX4620 is designed for single-supply operation ranging from +2V to +12V. The documentation specifies V+ and GND connections, with no mention of dual supply configurations.
