GENERAL DESCRIPTION

The ADG3300 is a bidirectional logic level translator that con­tains eight bidirectional channels. It can be used in multivoltage
digital system applications such as data transfer between a low
voltage DSP/controller and a higher voltage device. The internal
architecture allows the device to perform bidirectional logic
level translation without an additional signal to set the direction
of the translation.

The enable pin provides three-state operation of the Y side pins.

The ADG3300 is available in a compact 20-lead TSSOP package,
and it is guaranteed to operate over the 1.15 V to 5.5 V supply
voltage range and extended −40°C to +85°C temperature range.

PRODUCT HIGHLIGHTS

1. Bidirectional level translation.

2. Fully guaranteed over the 1.15 V to 5.5 V supply range.

3. No direction pin.

4. 20-lead TSSOP package.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability. Only one absolute maximum rating may be
applied at any one time.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
