Product Details
MAX4506CPA - Three-Channel Fault-Protected Signal-Line Protector
MAX4506CPA is a Maxim Integrated (now Analog Devices) three-channel, always-on signal-line protector in an 8-pin plastic DIP package, specified for 0°C to +70°C operation.
Use the complete ordering code and verify the circuit against the manufacturer's MAX4506/MAX4507 datasheet.
Overview
The MAX4506 provides three independent two-terminal analog signal paths that protect downstream circuitry from input overvoltage. During an input fault, the affected input path opens and its output is clamped toward the appropriate supply rail. The device does not require a logic control input; the channels operate when the supplies are applied.
Key Advantages
Each of the three signal inputs has an independent protected path.
Normal input signals can traverse the protected path across the supply range.
Inputs remain fault-protected when the device is unpowered, within specified limits.
There is no separate digital control input to route or sequence.
Feature Summary
IN1–OUT1, IN2–OUT2, and IN3–OUT3 are independent protected signal paths.
Input overvoltage protection is specified to ±36 V with power on and ±40 V with power off.
On-resistance is specified at 100 Ω maximum under the datasheet's electrical test conditions.
The CPA ordering suffix identifies an 8-pin plastic DIP, commercial-temperature option.
Package & Footprint
The MAX4506CPA ordering table identifies an 8-pin plastic DIP. The catalog package is 8-DIP (0.300 in, 7.62 mm), registered locally as 8-DIP.
- Confirm the 8-pin DIP pad pattern and 0.300-inch row spacing.
- Match pin 1 orientation and supply routing to the datasheet.
- Check board clearance and through-hole assembly requirements.
The package reference image is pending local asset completion; do not release this page until the JPG is present and verified.
Pin Functions
The following 8-pin DIP assignment is from the MAX4506 datasheet.
Protected signal inputs for channels 1 to 3.
Negative supply-voltage input.
Protected signal outputs for channels 3 to 1.
Positive supply-voltage input.
The datasheet instructs designers to connect unused inputs to a fixed voltage within the supply range.

Replacement Considerations
The MAX4506 family includes other temperature grades and package options, while MAX4507 has a different channel count and pinout. Do not assume these variants are interchangeable. For any replacement, compare the full ordering code, pin assignment, package footprint, operating temperature, supply range, fault limits, and assembly requirements. No unverified internal product link is provided.
Manufacturer Information
MAX4506CPA is documented in the Maxim Integrated MAX4506/MAX4507 datasheet, now hosted by Analog Devices. Refer to the latest manufacturer-controlled document and any applicable product notices before final design approval.
Applications
Protect sensitive measurement inputs exposed to abnormal field signals.
Isolate downstream analog stages during an input overvoltage event.
Address uncertain signal and power sequencing at module interfaces.
Protect analog signal paths in automated test setups.
Quality & Authenticity
Confirm the complete ordering code, package markings, pin-1 orientation, and lot documentation during receiving inspection. Electrical suitability and authenticity require normal engineering and procurement controls.
FAQ
How many channels does MAX4506CPA protect?
It provides three independent input-to-output signal paths.
Does the device need a logic-enable signal?
No. The protected paths are designed to be always on when the supply rails are present.
Is a MAX4507 a direct substitute?
No blanket substitution should be assumed: MAX4507 has eight channels and different package and pin assignments.
Is the package image ready?
The registered 8-DIP JPG must be supplied and verified before publication.
Engineering Notice
Verify the full electrical table, fault and recovery behavior, absolute maximum ratings, and PCB footprint against the manufacturer datasheet. The missing package JPG is a publication blocker.
