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.
PRODUCT HIGHLIGHTS
1. Bidirectional level translation matches any voltage level from
1.65 V to 3.6 V.
2. The device offers high performance and is fully guaranteed
across the supply range.
3. Short circuit protection.
4. Tiny SOT-23 package.
