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