GENERAL DESCRIPTION
The ADG3304 is a 4-Channel bidirectional level transla-
tor. Its function is to provide level shifting in a multi-
voltage system. The voltage applied to V
logic levels on the A side of the device, while V
the levels on the Y side. In this way, signals applied to the
V
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.
V
to V
lower than V
pulled low, the Ax and Yx inputs/outputs are tri-stated.
The EN pin is driven high for normal operation. EN pin
