General Description
The MAX4533 quad, single-pole/double-throw (SPDT),
fault-protected analog switch is pin-compatible with the
industry-standard MAX333 and MAX333A. The MAX4533
features fault-protected inputs and Rail-to-Rail
®
signal
handling. The normally open (NO_ ) and normally closed
(NC_ ) terminals are protected from overvoltage faults up
to ±25V with power on and up to ±40V with power off.
During a fault condition, NO_ and NC_ become high
impedance with only nanoamperes of leakage current
flowing to the source. In addition, the output (COM_)
clamps to the appropriate polarity supply rail and pro-
vides up to ±10mA of load current. This ensures unam-
biguous rail-to-rail outputs when a fault occurs.
The MAX4533 operates from dual ±4.5V to ±18V power
supplies or a single +9V to +36V supply. All digital inputs
have +0.8V and +2.4V logic thresholds, ensuring both
TTL and CMOS logic compatibility when using ±15V
supplies or a +12V supply. On-resistance is 175 max
and is matched between switches to 10 max. The off-
leakage current is only 0.5nA at T
A
= +25°C and 10nA at
T
A
= +85°C.

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_ or 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. Signals on NC_ or NO_ exceeding -25V to +25V may damage the device. These
limits apply with power applied to V+ or V-. The limit is ±40V with V+ = V- = 0.
