Fault-Protected, High-Voltage
Signal-Line Protectors
General Description
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 ±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 100Ω max and matched within
7Ω, and on-leakage is less than 0.5nA at T
A
= +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.
