GENERAL DESCRIPTION

The ADG3308 is an 8-Channel bidirectional level transla-

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

voltage system. The voltage applied to VCCA sets up the

logic levels on the A side of the device, while VCCY sets

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

VCCA side of the device appear as VCCY compatible logic

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.

VCCY operates from +1.65 to 5.5 V while VCCA from +1.2

to VCCY. VCCA must always operate from a supply that is

lower than VCCY. When the device Enable pin (EN) is

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

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

is referred to VCCY voltage.
