1) Input/output I or O = -0.3 to 3.6V, Is = -0.3 to 5.5V
2) Pins 32 and 33 are latch address setting input pins when pin 41 = "L".
3) Pin 34 is a demodulation function master or slave setting input pin when pin 41 = "L".
4) Pin 35 is a modulation function or general-purpose I/O function switch setting input pin when pin 41 = "L".
5) Perform ON/OFF for all power supplies with the same timing as a latch-up countermeasure.
