Signal-Line Circuit Protectors
_______________General Description
The MAX366 and MAX367 are multiple, two-terminal circuit
protectors. Placed in series with signal lines, each two-ter-
minal device guards sensitive circuit components against
voltages near and beyond the normal supply voltages.
These devices are used at interfaces where sensitive cir-
cuits are connected to the external world and could
encounter damaging voltages (up to 35V beyond the sup-
ply rails) during power-up, power-down, or fault conditions.
The MAX366 contains three independent protectors and
the MAX367 contains eight. They can protect analog sig-
nals using either unipolar (4.5V to 36V) or bipolar (±2.25V
to ±18V) power supplies. Each protector is symmetrical.
____________________________Features
o ±40V Overvoltage Protection
o Open Signal Paths with Power Off
100 ? Signal Paths with Power On
o 1nA Max Path Leakage at +25°C
o 44V Maximum Supply Voltage Rating
o Automatic Protection; No Programming or
Controls
______________Ordering Information
Input and output terminals may be freely interchanged.
These devices are voltage-sensitive MOSFET transistor
arrays that are normally on when power is applied and
normally open circuit when power is off. With ±10V sup-
plies, on-resistance is 100 ? max and leakage is less than
1nA at +25°C.
When signal voltages exceed or are within approximately
1.5V of either power-supply voltage (including when
power is off), the two-terminal resistance increases dra-
matically, limiting fault current as well as output voltage to
sensitive circuits. The protected side of the switch main-
tains the correct polarity and clamps approximately 1.5V
below the supply rail. There are no “glitches” or polarity
reversals going into or coming out of a fault condition.
