6.4 Driver I/O circuit and example connection
Input signal
The driver’s signal input is a C-MOS input. The signal status indicates “0 to 0.5 V (L
level) when ON,” or “4 to 5 V (H level) when OFF.”

Output signal
The driver’s signal output is a transistor open-collector output. The signal status
does not indicate the voltage level of the signal, but it indicates “ON (energized)” or
“OFF (not energized)” of the internal transistor.
