MAX4620EPD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4620EPD+ is a quad single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +2V to +12V single supply and features ±15kV ESD protection on NO/NC pins. The device offers a maximum on-resistance of 70Ω at 5V, with typical matching of 0.5Ω and flatness of 2Ω. Leakage current is guaranteed at 0.5nA at +25°C. Switching times are 150ns turn-on and 80ns turn-off at 5V. It uses a 14-pin DIP package and functions within a -40°C to +85°C temperature range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EPD' confirms the 14-pin PDIP package variant. Confirm the 'E' suffix indicates the extended industrial temperature range of -40°C to +85°C. Ensure compatibility with existing PCB footprints designed for standard DIP-14 packages. Check RoHS compliance status if required by local regulations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when rail-to-rail signal integrity is critical in low-voltage environments. Consider the 70Ω max on-resistance for applications where signal attenuation must be minimized. Evaluate the 0.5nA leakage specification for high-impedance sensor interfaces. Verify that the 14-pin DIP form factor fits the mechanical constraints of the target assembly.

Analog Switches, Multiplexers, Demultiplexers Part Context

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

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly identifies the MAX4620 as a pin-compatible replacement for the 74HC4066, MAX4066, and MAX4610/MAX4611/MAX4612. Designers replacing these legacy parts should verify that the improved ESD protection and lower on-resistance meet system requirements.
