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 provides up to ±10mA of load current. This ensures unambiguous rail-to-rail outputs when a fault occurs
