THEORY OF OPERATION

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

flow only from A to Y.

By limiting the current delivered into the load, for example,

current overload, which can occur when the Y pin is

The short-circuit protection circuitry works by limiting

the output current when the output voltage exceeds
