MAX4535EUD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4535EUD+ is a dual 2-to-1 fault-protected multiplexer in a 14-pin TSSOP package. It operates with ±4.5V to ±20V dual supplies or +9V to +36V single supply. Key electrical parameters include a maximum on-resistance of 400Ω and channel matching of 10Ω max. The device supports rail-to-rail signal handling with overvoltage clamping at 150mV beyond the rails. Fault protection provides ±40V tolerance with power off and ±25V with power on. Typical timing includes a 275ns turn-on time, 200ns turn-off time, and 20ns fault response time.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EUD corresponds to the 14-TSSOP package and -40°C to +85°C temperature range. Confirm RoHS compliance status as indicated in official documentation. Ensure the component source is an authorized distributor to guarantee authenticity. Check for any obsolescence notices from Analog Devices regarding this specific part number before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4535EUD+ when dual independent 2-to-1 switching with high-voltage fault protection is required. Choose this part over non-fault-protected switches if input signals may exceed supply rails. Verify that the 400Ω on-resistance meets system loss requirements. Ensure the operating temperature range of -40°C to +85C aligns with environmental conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4535EUD+ belongs to the MAX4534/MAX4535 family of fault-protected multiplexers. It is the dual-channel variant of the MAX4534 single 4-to-1 multiplexer. Both parts share identical fault protection mechanisms and electrical characteristics. The E suffix denotes the extended temperature range, while UD specifies the TSSOP package.

Analog Switches, Multiplexers, Demultiplexers FAQ

Are the COM pins fault protected?

No, the COM pins are not fault protected. Exceeding supply voltages on COM pins can damage the device through internal ESD diodes.

What is the recovery time after a fault condition?

Recovery time depends on the fault polarity. Positive faults typically recover in 2.5µs, while negative faults recover in 1.3µs.

How does the device handle signals beyond the supply rails?

During normal operation, it passes rail-to-rail signals. During fault conditions where NO_ exceeds rails, the output is clamped to the appropriate supply voltage.
