1) Withstand voltage input/output: I or O
= −
0.3 to 3.6V, I5
= −
0.3 to 5.5V
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.
