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

capability. The input pins are protected from overvoltage

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

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 (+9V to +36V) or bipolar

(±8V to ±18V) power supplies.

These devices have no logic control inputs; the protec-

tors are designed to be always-on when the supplies

are on. On-resistance is 100

7 , and on-leakage is less than 0.5nA at T

The MAX4506 is available in 8-pin SO/DIP packages.

The MAX4507 is available in 20-pin SSOP and 18-pin

SO/DIP packages.
