MAX4630EPD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4630EPD is a quad, single-pole/single-throw (SPST) CMOS analog switch in a 14-pin DIP package. It features normally closed (NC) contacts and operates on a single +2V to +12V supply. Key electrical parameters include an on-resistance of 70Ω max at 5V, off-leakage current of 0.5nA at +25°C, and a -3dB bandwidth exceeding 300MHz. The device provides ±15kV ESD protection on signal pins, handles rail-to-rail signals, and draws 0.5µW power. It functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EPD' corresponds to the 14-pin PDIP package when sourcing. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the component meets the specified -40°C to +85°C operating temperature range required for the application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for low-voltage, single-supply applications requiring quad SPST switching. It is appropriate where TTL/CMOS logic compatibility and high ESD immunity are critical. Consider the 70Ω on-resistance limit and 300MHz bandwidth against system requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4620/MAX4630/MAX4640 family of low-voltage, high-ESD-protected analog switches. The MAX4630 variant specifically utilizes four normally closed switches, distinguishing it from the MAX4620 (normally open) and MAX4640 (mixed configuration).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the MAX4630EPD as a pin-compatible replacement for the 74HC4066, MAX4066, and other MAX461x series devices. Verify pinout alignment before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4630 and MAX4620?
