MAX4534EPD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4534EPD is a single 4-to-1 fault-protected multiplexer housed in a 14-pin Plastic DIP package. It operates with ±4.5V to ±20V dual supplies or +9V to +36V single supply, covering an industrial temperature range of -40°C to +85°C. The device features ±40V overvoltage protection when power is off and ±25V protection when power is on. Key electrical parameters include a maximum on-resistance of 400 Ω, channel-to-channel matching of 10 Ω max, and typical enable turn-on/off times of 275 ns and 200 ns respectively.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EPD confirms the 14-pin Plastic DIP package and -40°C to +85°C operating temperature range. Confirm that the component is sourced from authorized distributors to ensure authenticity, as this part may be subject to obsolescence notices. Check for RoHS compliance status if required by your manufacturing standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4534EPD when a single 4-to-1 multiplexing function is required with high-voltage fault protection. Ensure the application demands rail-to-rail signal handling and TTL/CMOS logic compatibility. Verify that the 400 Ω maximum on-resistance meets the system's signal integrity requirements and that the 14-pin DIP package fits the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4534EPD belongs to the MAX4534/MAX4535 family of fault-protected, high-voltage multiplexers manufactured by Analog Devices Inc./Maxim Integrated. This series distinguishes itself through parallel FET construction for low resistance and robust overvoltage clamping capabilities, designed for demanding industrial and avionics environments requiring reliable signal switching under fault conditions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacement options within the same family include the MAX4534CUD (TSSOP) and MAX4534ESD (Narrow SO). Note that these alternatives differ in package type and potentially temperature range compared to the EPD variant. Verify pinout compatibility and thermal characteristics before substitution.
