MAX4507EAP+

Specialized ICS Overview

The MAX4507EAP+ is a fault-protected, high-voltage signal-line protector containing eight independent two-terminal analog switches. It provides overvoltage protection up to ±36V with power on and ±40V with power off. The device features rail-to-rail signal handling, an on-resistance of 100Ω maximum matched within 7Ω, and on-leakage less than 0.5nA at +25°C. It operates on unipolar (+9V to +36V) or bipolar (±8V to ±18V) supplies without logic control inputs. Packaged in a 20-pin SSOP, it ensures unambiguous outputs during faults by clamping to supply rails.

Specialized ICS Procurement Notes

Verify the component status as obsolete based on local distributor records. Confirm the package type is 20-SSOP and check for RoHS compliance documentation. Ensure the specific suffix EAP+ matches the required temperature range and packaging format before procurement.

Specialized ICS Selection Notes

Select this part when protecting sensitive downstream circuitry from high-voltage transients on analog signal lines. It is suitable for applications requiring fault-protected multiplexers or switches that must handle signals exceeding standard supply rails. Verify that the single-channel configuration per protector meets the system's channel count requirements.

Specialized ICS Part Context

The MAX4507EAP+ belongs to the MAX4506/MAX4507 family of fault-protected signal-line protectors. It is pin-compatible with industry-standard MAX366/MAX367 devices. The MAX4507 variant specifically contains eight independent protectors, whereas the MAX4506 contains three.
