The ADG3304 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 DSP/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-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 (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 is available in compact 14-lead TSSOP and 12-bump WLCSP packages. It is 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.
