The MAX4533 is not a lightning arrester or surge pro-
tector. Exceeding the fault-protection voltage limits on
NO_ or NC_, even for very short periods, can cause the
device to fail.
There is no connection between the analog signal
paths and GND. The analog signal paths consist of an
N-channel and P-channel MOSFET with their sources
and drains paralleled and their gates driven out of
phase to V+ and V- by the logic-level translators.
V+ and GND power the internal logic and logic-level
translators and set the input logic thresholds. The logic-
level translators convert the logic levels to switched V+
and V- signals to drive the gates of the switches. This

drive signal is the only connection between the power
supplies and the analog signals. GND, IN_, and COM_
have ESD protection diodes to V+ and V-.
When the logic signals are driven rail-to-rail from 0 to
+12V or -15V to +15V, the supply current reduces to
approximately half of the supply current when the logic
input levels are at 0 to 5V.
The MAX4533 operates with bipolar supplies between
±4.5V and ±18V. The V+ and V- supplies need not be
symmetrical, but their difference can not exceed the
absolute maximum rating of +44V. The MAX4533 oper-
ates from a single supply between +9V and +36V when
V- is connected to GND.
