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, VCC1 for A and
VCC2 for Y. The signal path is unidirectional, meaning data can
flow only from A to Y.
The ADG3231 can operate with any combination of VCC1
and VCC2 supply voltages within the 1.65 V to 3.6 V range,
allowing the part to perform either up (VCC1 < VCC2) or down
(VCC1 > VCC2) level translation. The output stage is protected

against current overload, which can occur when the Y pin is
accidentally shorted to the VCC2 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.

Data Sheet
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Only one absolute maximum rating may be applied at any one
time.
