ADG3300BRUZ (ANALOG DEVICES)

The ADG3300BRUZ is a 8-channel Bidirectional Logic Level Translator used in multivoltage digital system applications such as data transfer between a low voltage DSP/controller and a higher voltage device. 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-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 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 6kR resistors, while the Y terminals are in the high impedance state. The EN pin is referred to VCCA supply voltage and driven high for normal operation.
