GENERAL DESCRIPTION
The ADG3232 is a level translator 2-1 mux designed on a sub-
micron process and operates from supplies as low as 1.65 V. The
device is guaranteed for operation over the supply range 1.65 V to
3.6 V. It operates from two supply voltages, allowing bidirectional
level translation, i.e., it translates low voltages to higher voltages
and vice versa. The signal path is unidirectional, meaning data
may flow only from A to Y.
This type of device may be used in applications requiring commu-
nication between devices operating from different supply levels.
The level translator mux is packaged in one of the smallest foot-
prints available for its pin count. The 8-lead SOT-23 package
requires only 8.26 mm  8.26 mm of board space.

... CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADG3232 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges.Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...
