GENERAL DESCRIPTION
The ADG3231
submicron process that is guaranteed to operate over the 1.65 V
to 3.6 V supply range. The device can be used in applications
requiring communication between digital devices operating
from multiple supply voltages. The logic levels on each side of
the device are set by the two supply voltages, V
V
flow only from A to Y.
The ADG3231 can operate with any combination of V
and V
allowing the part to perform either up (V
(V
against current overload, which can occur when the Y pin is
accidentally shorted to the V
