GENERAL DESCRIPTION
The ADG3304 is a bidirectional logic level translator that con-
tains 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 VCCA sets the logic levels on the A side of
the device, while VCCY sets the levels on the Y side. For proper
operation, VCCA must always be less than VCCY. The VCCA-com-
patible logic signals applied to the A side of the device appear as
VCCY-compatible levels on the Y side. Similarly, VCCY-compatible
logic levels applied to the Y side of the device appear as VCCA-
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 VCCA supply voltage and
driven high for normal operation.
The ADG3304 is available in compact 14-lead TSSOP, 12-ball
WLCSP, and 20-lead LFCSP. It is guaranteed to operate over
the 1.15 V to 5.5 V supply voltage range.
