GENERAL DESCRIPTION
The ADG3231 is a single-channel level translator designed on a
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_CC1 for A and
V_CC2 for Y. The signal path is unidirectional, meaning data can
flow only from A to Y.
The ADG3231 can operate with any combination of V_CC1
and V_CC2 supply voltages within the 1.65 V to 3.6 V range,
allowing the part to perform either up (V_CC1 < V_CC2) or down
(V_CC1 > V_CC2) level translation. The output stage is protected

against current overload, which can occur when the Y pin is
accidentally shorted to the V_CC2 or GND rails.
The ADG3231 is available in the SOT-23 (2.8 mm × 2.9 mm
× 1.3 mm) ultracompact package, making the part ideal for
applications where space is critical.
