GENERAL DESCRIPTION
The ADG3308/ADG3308-1 are bidirectional level translators
containing eight bidirectional channels. They can be used in
multivoltage digital system applications, such as a data transfer
between a low voltage DSP controller and a higher voltage device.
The internal architecture allows the device to perform
bidirectional 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, and VCCY sets the levels on the Y side. For proper
operation, VCCA must always be less than VCCY. The VCCA
compatible 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. For normal operation, EN should be driven high.
The ADG3308 is available in a compact 20-lead TSSOP and
a 20-lead LFCSP. The ADG3308-1 is available in a 20-ball
WLCSP. The EN pin is referred to the VCCY supply voltage
for the ADG3308 and to the VCCA supply voltage for the
The ADG3308/ADG3308-1 are guaranteed to operate over the
1.15 V to 5.5 V supply voltage range and the extended 40°C to
+85°C temperature range.
