8. NOTE ON CORRECT USE
8.1 Transmitting Data
Data input at reset state is ignored.
8.2 Pin Processing of Unused Circuit
The input/output pins of an unused circuit must be processed as specified below.
A V
M
power supply pin is provided for each output circuit. The current consumption of the internal circuit can be
reduced by dropping the V
M
power of the unused circuit to GND. However, if there are multiple power supply pins, be
sure to connect all of them to the same potential.

8.3 Input Pin Processing
The signal input pins for this IC are not equipped with on-chip pull down/pull up resistors. When the V
DD
power is on,
the logic for all of the input pins must be set to either H or L.
