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.
