Note:
1. Two card-edge I/Os – one for odd channels and another for even - have the same pinouts.
2. There are two identical chips (with 96 high voltage outputs) on each driver.
? COM, VCOM & GND have multiple lines to carry enough current. They are connected
between the two chips in the driver. ? The data_in (SD1 & SD2) are connected to chip 1 only, and the data_out lines are
connected to the chip 2 i.e. cascaded. ? Other lines (Vh, Vcc, SLn, MN0, MN1, MN2, MN3, A/B & SCK) are not connected in the
driver, and should be connected on the user board .

1. The absolute maximum rating specifies “non-damaging condition”. Proper operation of the driver is
not guaranteed under this condition. 2. The supply voltages should be Vh > Vcc > GND during operation.
3. Power on cycle should be Vcc on first, and then Vh on. Power off cycle should be Vh off first, and
then Vcc off.
Operating conditions (Ip, Ta and duty cycle) should be controlled so that Tj (junction temperature) does
not exceed the rating.
