Fault-Protected / High-Voltage Signal-Line Protectors
General DescriptionThe 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 ±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 100Wmax and matched within, and on-leakage is less than 0.5nA at TA= +25°C.
The MAX4506 is available in 8-pin SO/DIP packages.
The MAX4507 is available in 20-pin SSOP and 18-pin
SO/DIP packages.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS(V+ = +15V, V- = -15V, TA= TMINto TMAX, unless otherwise noted. Typical values are at TA= +25°C.) (Note 3)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: OUT_ pins are not fault protected. Signals on OUT_ exceeding V+ or V- are clamped by internal diodes. Limit forward-diodecurrent to maximum current rating.
Note 2: IN_ pins are fault protected. Signals on IN_ exceeding -36V to +36V may damage the device. These limits apply with powerapplied to V+ or V-, or ±40V with V+ = V- = 0.
