GENERAL DESCRIPTIONS
The ADG3304-EP is a bidirectional logic level translator that
contains four bidirectional channels. It can be used in
multivoltage digital system applications, such as data transfer,
between a low voltage digital signal processing controller and a
higher voltage device using SPI and MICROWIRE interfaces.
The internal architecture allows the device to perform
bidirectional logic level translation without an additional signal
to set the direction in which the translation takes place.
The voltage applied to V
CCA
sets the logic levels on the A side of
the device, while V
CCY
sets the levels on the Y side. For proper
operation, V
CCA
must always be less than V
CCY
. The V
CCA
-com-
patible logic signals applied to the A side of the device appear as
V
CCY
-compatible levels on the Y side. Similarly, V
CCY
-compatible
logic levels applied to the Y side of the device appear as V
CCA
-
compatible logic levels on the A side.
The enable pin (EN) provides three-state operation on both the
A side and the Y side pins. When the EN pin is pulled low, the
terminals on both sides of the device are in the high impedance
state. The EN pin is referred to the V
CCA
supply voltage and
driven high for normal operation.
The ADG3304-EP is available in compact 14-lead TSSOP
package.
Full details about this enhanced product are available in the
ADG3304 data sheet, which should be consulted in conjunction
with this data sheet.
