Product Details
MAX4507CAP - Eight-Channel Fault-Protected Signal-Line Protector
The Maxim Integrated MAX4507CAP is an eight-channel, always-on analog signal-line protector in a 20-SSOP package, specified for 0 °C to +70 °C operation.
Technical characteristics and the exact order code are taken from the manufacturer MAX4506/MAX4507 Rev. 2 data sheet. Check current controlled documentation and the received device before design release.
Overview
MAX4507CAP places eight independent two-terminal protection paths between exposed analog inputs and downstream circuits. With supplies applied, normal signals pass through the paths. An overvoltage on an IN pin opens that channel's input path while the associated OUT pin is driven toward the appropriate supply rail. The inputs retain fault protection when power is off.
Key Advantages
Protects up to eight analog signal paths without a shared logic-select scheme.
Manufacturer-rated IN-pin fault range is ±36 V with power on and ±40 V with power off.
During an input fault, the associated output is clamped toward a supply rail rather than left ambiguous.
An overvoltage on one input does not disturb an otherwise-on channel, subject to the specified supply and load conditions.
Feature Summary
Supports single-supply +9 V to +36 V or dual-supply ±8 V to ±18 V operation under the data-sheet conditions.
Rail-to-rail analog handling with 100 Ω maximum on-resistance stated by the manufacturer.
Signal paths open when supplies are off; input fault protection remains specified.
The CAP order code identifies the 20-pin, 5.3 mm-body SSOP variant in the manufacturer's ordering table.
Package & Footprint
The manufacturer lists MAX4507CAP as a 20-pin SSOP. The LCDChip database and package registry identify it as 20-SSOP (0.209", 5.30 mm width). The manufacturer's SSOP outline is a nominal 5.3 mm body with 0.65 mm lead pitch. Use the current controlled package drawing to confirm the land pattern and dimensions.
- Verify the SSOP pin-one indicator and 20-lead footprint.
- Confirm 0.65 mm lead pitch and 5.3 mm nominal body width.
- Keep V+ and V− supply bypassing close to their pins.
- Separate fault-exposed IN traces from protected OUT circuitry.
The registered 20-SSOP JPG is missing and must be supplied and checked before publication.
Pin Functions
The following pin groups use the manufacturer's 20-pin SSOP pin-description column, not the 18-pin SO/DIP mapping.
Fault-protected analog inputs for channels 1 through 3.
Fault-protected analog inputs for channels 4 through 8.
Negative supply connection for dual-supply use, or the low rail for single-supply operation.
No internal connection; follow the manufacturer's PCB guidance.
Protected-circuit outputs for channels 8 through 4, in descending order.
Protected-circuit outputs for channels 3 through 1.
Positive supply connection.
Tie unused inputs to a firm voltage within the supply range as directed in the pin-description note. OUT pins are not fault protected.

Compare each electrical value with the detailed data-sheet test circuit, supply condition and temperature column. Absolute-maximum stress limits are not normal operating settings.
Replacement Considerations
The manufacturer describes MAX4507 as pin-compatible with MAX367 at the family level, but that statement alone does not establish a complete-order-code drop-in replacement. MAX4507EAP is another 20-SSOP option with a different temperature grade; the 18-pin SO/DIP MAX4507 options require a different footprint and pin map. Check fault thresholds, supply range, channel count, temperature grade, package, finish and qualification before any substitution. No unverified LCDChip product link is provided.
Manufacturer Information
MAX4507CAP appears as an exact order code in the Maxim Integrated MAX4506/MAX4507 Rev. 2 data sheet, hosted by Analog Devices. That controlled document supplies the pin map, electrical characteristics, applications and SSOP package drawing. Confirm present orderability and compliance separately for a purchasing decision.
Applications
Guard measurement inputs against overvoltage events while preserving normal analog signal paths.
Protect downstream circuitry in modular systems where power and signal connections can be sequenced unpredictably.
Provide defined clamping behavior for fault-exposed analog lines within the specified supply and load limits.
Quality & Authenticity
Check the full MAX4507CAP marking, 20-lead SSOP body, pin-one orientation and traceability against current manufacturer documentation. This description does not certify the provenance or condition of any individual unit.
FAQ
How many lines does MAX4507CAP protect?
It has eight independent analog signal-line protection channels.
Are the OUT pins fault protected?
No. The manufacturer's notes identify the IN pins as fault protected; OUT pins require normal downstream voltage and current design limits.
Does this part need a logic enable signal?
No. The protection channels are designed to remain on whenever the supply rails are applied.
Engineering Notice
Review the manufacturer's current MAX4506/MAX4507 data sheet for supply sequencing, fault conditions, unused input handling and the exact 20-SSOP pin assignment. The package illustration is missing locally, so visual package verification remains incomplete. This page is not a substitute for the controlled data sheet.
