Analog Devices Inc./Maxim Integrated MAX4507CPN+

The MAX4507 provides eight protected signal paths between IN1-IN8 and OUT1-OUT8. Under normal input conditions each channel passes an analog signal through an internal switch. A fault drives the corresponding output toward the supply rail instead of passing the full overvoltage to downstream circuitry. The device is intended for protection of multiplexers, data-acquisition inputs and related analog interfaces, subject to the limits in the official data sheet.

The official ordering table identifies MAX4507CPN+ as an 18-pin plastic DIP for 0 °C to +70 °C operation. The LCDChip package registry maps the database description 18-DIP (0.300 in, 7.62 mm) to 18-DIP and the expected JPG path below. Match the supplier's top marking and the manufacturer's mechanical drawing before assembly.

Layout checks

• Verify pin-1 orientation and 18-pin numbering.
• Confirm row spacing, body dimensions and lead geometry against the controlled outline.
• Keep fault-current paths within the manufacturer's limits.

The registered 18-DIP JPG is currently missing; this draft must not be published until the image is available and checked.

The MAX4507 18-pin DIP/SO pin table assigns eight input/output channel pairs and two supply pins:

Use the official pin table and package drawing for PCB sign-off; the groups above are not a footprint drawing.

Electrical values summarize the Analog Devices MAX4506/MAX4507 Rev. 2 data sheet. Recheck test conditions, absolute limits and typical-versus-maximum design margins in the original tables.

No pin-for-pin replacement is qualified here. Other MAX4507 package or temperature options may differ in footprint and order status. MAX4506 is a related fault-protected family member with a different channel configuration, not an assumed direct substitute. Compare channel count, pinout, supply rails, fault voltage, on-resistance, temperature grade and lifecycle before redesign.

No internal alternative-product link is included because no exact qualified replacement was verified in the local catalog.

Analog Devices hosts the official MAX4506/MAX4507 Rev. 2 data sheet and a current MAX4507 family page. A Maxim/Analog Devices product-discontinuance notice lists the exact MAX4507CPN+ order code. The family-level production label must not be applied to this discontinued option.

Because the exact order code is discontinued, check complete marking, lot and date code, chain of custody, lead condition, storage history and electrical screening before use. A distributor listing does not by itself demonstrate authorized current production. Confirm stock and current tier prices directly before quoting.

Use the official data sheet and package drawing for final design decisions. The displayed catalog inventory and unit price are unverified legacy values, not a current distributor quote. Resolve the missing package JPG and obtain live stock/tier-price evidence before release.
