MAX4640EPD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4640EPD is a high-speed, low-voltage CMOS analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features four independent single-pole single-throw (SPST) channels within a single package. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 70 Ohms and a typical on-resistance match of 10 mOhm across channels. Switching times are characterized by a maximum turn-on time of 100 ns and a maximum turn-off time of 80 ns. The component supports a continuous DC current of 50 mA per channel and dissipates up to 625 mW of power. It functions reliably within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EPD to confirm the package type and temperature grade against the official datasheet. Confirm RoHS compliance status as manufacturing processes may vary. Check for obsolescence notices or lifecycle changes directly from Analog Devices documentation before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated analog switches are required in a single footprint. Ensure the application voltage stays within the 2.7 V to 5.5 V range. Verify that the 70 Ohm on-resistance meets the signal integrity requirements of the target circuit compared to lower-resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX464x family of high-speed CMOS analog switches. It shares functional similarities with other members like the MAX4641 and MAX4642 but differs in channel count and configuration. The EPD designation typically indicates a PDIP package variant suitable for through-hole mounting.
