Fault-Protected, High-Voltage, Dual Analog Switches
General DescriptionThe MAX4631/MAX4632/MAX4633 high-voltage, dual
analog switches are pin compatible with the industry-stan-
dard DG401/DG403/DG405. They upgrade the existing
devices with fault-protected inputs and Rail-to-Rail®signal
handling capabilities. The MAX4631/MAX4632/MAX4633’s
normally open (NO) and normally closed (NC) terminals
are protected from overvoltage faults up to 36V during
power-up or power-down. During a fault condition, these
terminals become open circuit and only nanoamperes of
leakage current flow from the source, yet the switch output
(COM_) continues to furnish up to 18mA of the appropri-
ate polarity supply voltage to the load. This ensures unam-
biguous rail-to-rail outputs when a fault begins and ends.
On-resistance is 85Ω(max) at +25°C and is matched
between switches to 6Ω(max). Off-leakage current is only
0.5nA at +25°C and 5nA at +85°C.
The MAX4631 has two NO single-pole/single-throw (SPST)
switches. The MAX4632 has two NO/NC single-pole/
double-throw (SPDT) switches. The MAX4633 has two NO
double-pole/single-throw (DPST) switches.
These CMOS switches operate with dual power supplies
ranging from ±4.5V to ±18V or a single supply between
+9V and +36V. All digital inputs have +0.8V and +2.4V
logic thresholds, ensuring both TTL- and CMOS-logic
compatibility when using ±15V or a single +12V supply.

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:COM_ and IN_ pins are not fault protected. Signals on COM_ to IN_ exceeding V+ or V- are clamped by internal diodes.
Limit forward diode current to maximum current rating.
Note 2:NC_ and NO_ pins are fault protected (see Electrical Characteristics). With power applied to V+ or V-, signals on NC_ or
NO_ exceeding ±25V (MAX4632) or ±36V (MAX4631/MAX4633) may damage the device. With V+ = V- = 0, signals on NC_
or NO_ exceeding ±40V may damage the device.
