The ADG3300 is a bidirectional logic level translator that con-tains 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 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-compatible 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 provides three-state operation of the Y side pins. When the enable pin (EN) is pulled low, the A1 to A8 pins are internally pulled down by 6 kΩ resistors, while the Y terminals are in the high impedance state. The EN pin is referred to V_CCA supply voltage and driven high for normal operation.

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.
