GENERAL DESCRIPTION

The ADG3231 is a level translator designed on a submicron

process that 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 A1 to Y1.

This type of device may be used in applications requiring commu-

nication between devices operating from different supply levels.

The level translator is packaged in one of the smallest footprints

available for its pin count. The 6-lead SOT-23 package requires

only a maximum of 5.28 mm

5.28 mm 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.
