• Description: Digital Audio Interface Transceiver
• Manufacturer: SANYO [Sanyo Semicon Device]

Continued from preceding page.
1) Withstand voltage input/output: I or O = -0.3 to 3.6V, I
2) Pins 32 and 33 are input pins for chip address setting, when pin 41 = "L".
3) Pin 34 is a demodulation function master or an input pin for slave setting, when pin 41 = "L".
4) Pin 35 is a modulation function or an input pin for general-purpose I/O function switch setting, when pin 41 = "L".
5) ON/OFF for all power supplies must be done at the same timing as a latch-up countermeasure.
Pin No.
