The ADG3308 is an 8-Channel bidirectional level translator. Its function is to provide level shifting in a multivoltage system. The voltage applied to VCCA sets up the logic levels on the A side of the device, while VCCY sets the levels on the Y side. In this way, signals applied to the VCCA side of the device appear as VCCY compatible logic on the other side of the device and vice versa as the device is designed to handle bidirectional signals. The device is guaranteed for operation over the supply range 1.2 V to 5.5 V.
