Fault-Protected, High-Voltage

Signal-Line Protectors

General Description

Features

The MAX4506/MAX4507 multiple, two-terminal signal-line

protectors are pin-compatible with the industry-standard

MAX366/MAX367. These new circuit protectors feature

fault-protected inputs and Rail-to-Rail^®signal handling

capability. The input pins are protected from overvoltage

faults up to ±36ꢀ with power on or ±40ꢀ with power off.

During a fault condition, the input terminal becomes an

open circuit and only nanoamperes of leakage current

flow from the source; but the switch output (OUT_) fur-

nishes typically 19mA from the appropriate polarity sup-

ply to the load. This ensures unambiguous rail-to-rail

outputs when a fault begins and ends.

ꢀ Overvoltage Protection

ꢀ Any On Channel Output is Not Affected

by an Overvoltage to Any Other Channel

ꢀ 100Ω max On-Resistance

ꢀ 10ns Overvoltage Turn-On Delay

ꢀ No Latchup During Power Sequencing

ꢀ Rail-to-Rail Signal Handling

The MAX4506 contains three independent protectors

while the MAX4507 contains eight independent protec-

tors. They can protect both unipolar and bipolar analog

signals using either unipolar (+9ꢀ to +36ꢀ) or bipolar

(±±ꢀ to ±1±ꢀ) power supplies.

ꢀ 500Ω Output Clamp Resistance During

Overvoltage

These devices have no logic control inputs; the protec-

tors are designed to be always-on when the supplies

are on. On-resistance is 100Ω max and matched within

Ordering Information

7Ω, and on-leakage is less than 0.5nA at T = +25°C.

The MAX4506 is available in ±-pin SO/DIP packages.

The MAX4507 is available in 20-pin SSOP and 1±-pin

SO/DIP packages.
