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.
