GENERAL DESCRIPTION

The ADG3308 is an 8-Channel bidirectional level transla-

tor. Its function is to provide level shifting in a multi-

the levels on the Y side. In this way, signals applied to the

on the other side of the device and vice versa as the device

is designed to handle bidirectional signals. The device is

guaranteed for operation over the supply range 1.2 V to

5.5 V.

These devices are suited to applications like data transfer

between a low voltage DSP/Controller and a higher

voltage device. Other applications include high end

consumer products where constant changes to the chipset

desgins result in multiple supply levels in the application.

pulled low, the Ax and Yx inputs/outputs are tri-stated.

The EN pin is driven high for normal operation. EN pin
