MAX4534ESD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4534ESD+ is a single 4-to-1 fault-protected multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with ±4.5V to ±20V dual supplies or +9V to +36V single supply. The device features 400 Ω maximum on-resistance and 2 Ω channel-to-channel matching. It provides ±40V overvoltage protection when power is off and ±25V protection when supplies are active. Key electrical parameters include 1pC charge injection, 5pF/6.5pF NO_/COM_ off-capacitance, and -53dB crosstalk at 1MHz. Switching times are 275ns (Ton) and 200ns (Toff). It is housed in a 14-SOIC package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'ESD+' corresponds to the 14-pin Narrow SOIC package and the industrial temperature grade (-40°C to +85°C). Confirm that the component is lead-free and RoHS compliant as indicated by the '+' designation. Ensure the source documentation matches the manufacturer's official datasheet specifications for this exact part number variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4534ESD+ when a single 4-to-1 multiplexing configuration is required with high-voltage fault protection capabilities. This part is suitable for applications requiring rail-to-rail signal handling and TTL/CMOS logic compatibility. Consider the 400 Ω on-resistance and switching speeds against system bandwidth requirements. Verify that the 14-SOIC package dimensions fit the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4534 belongs to a family of fault-protected, high-voltage multiplexers from Maxim Integrated. The MAX4535 is the dual 2-to-1 counterpart within the same series. Both devices share similar fault protection architectures and electrical characteristics but differ in channel configuration and pinout. The ESD suffix specifically denotes the narrow SOIC package option available for this model.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers: MAX4534CSD+, MAX4534EUD+. These variants offer the same functional specifications but may differ in package type (SOIC vs TSSOP) or temperature range.
