Analog Devices Inc./Maxim Integrated MAX4507EAP

The MAX4507 contains eight independent, two-terminal analog signal-line protectors. With appropriate power applied, each path conducts an in-range signal through its internal resistance. When an input exceeds a supply rail, the affected input path opens and its output is clamped toward the applicable rail. The device needs no separate logic-control input; the protection channels operate while the supplies are present.

The catalog package is 20-SSOP (0.209 inch, 5.30 mm width). The manufacturer's ordering table explicitly lists MAX4507EAP in 20-pin SSOP, and its package outline is the 5.3 mm SSOP drawing. Verify the manufacturer's controlled outline, lead pitch, land pattern, and pin-1 orientation for assembly.

Layout checks

• Confirm 20-pin SSOP orientation and footprint.
• Decouple V+ and V- near the device.
• Keep fault-current return paths controlled.
• Account for signal-path resistance in the analog error budget.

The registered 20-SSOP JPG is missing locally and returns HTTP 404 on the production site; publication is blocked until the image is restored and verified.

The 20-pin SSOP has eight input/output protection pairs, two supply pins, and two no-connect positions. Use the MAX4507 SSOP top-view drawing for exact numbered pad assignments; do not reuse the different 18-pin SO/DIP pinout.

Protection figures describe the IN terminals, not unrestricted survivability of the OUT terminals. Check the complete electrical table, current limits, load, and power-sequencing conditions.

Other MAX4507 order codes exist in different packages and grades. The datasheet discusses relation to MAX366/MAX367, but any substitution requires verification of exact package, pin numbering, rail range, fault behavior, output-clamp current, analog resistance, temperature grade, and qualification. No unverified internal product link or unconditional drop-in assertion is provided.

MAX4507 originated with Maxim Integrated and is documented on Analog Devices' MAX4507 product page. The manufacturer's MAX4506/MAX4507 datasheet identifies MAX4507EAP as the E-temperature 20-SSOP variant. Confirm current lifecycle notices and controlled documentation during sourcing and design review.

At incoming inspection, verify the exact MAX4507EAP order marking, 20-pin SSOP body, pin-1 orientation, lot traceability, and applicable manufacturer documentation. This listing does not prove authorized-channel origin or fitness for a specific system; validate the actual parts and completed circuit.

Design surge suppression, supply rails, OUT-pin current limiting, and PCB clearances for the actual system fault environment. The device is not a substitute for all external protection. Consult the current manufacturer datasheet and perform electrical and safety validation. Publication remains blocked until the registered production package JPG is available and correct.
