Note:
This voltage should be applied across V0 and GND. The following voltages are output to the V1,
V2, V3A (V3B) and V4 pins:
1/4 bias (V
2 and V3B are short-circuited)
V1 =3 V0/4 ±0.15 V
V2 = V3B = V0/2 ±0.15 V
V4 = V0/4 ±0.15 V
1/5 bias (V
3A and V3B are short-circuited)
V1 = 4 V0/5 ±0.15 V
V2 = 3 V0/5 ±0.15 V
V3A = V3B = 2 V0/5 ±0.15 V
V4 = V0/5 ±0.15 V
The voltages at the V0, V1, V2, V3A (V3B), V4 and GND pins should satisfy
V0 > V1 > V2 > V3A (V3B) > V4 > GND

* If the chip is attached on a substrate using COG technology, the chip tends to be susceptible
to electrical characteristics of the chip due to trace resistance on the glass substrate. It is
recommended to use the chip by confirming that it operates on the glass substrate properly.
Trace resistance, especially, VDD and VSS trace resistance, between the chip on the LCD
panel and the flexible cable should be designed as low as possible. Trace resistance that
cannot be very well decreased, larger size of the LCD panel, or greater trace capacitance
between the microcontroller and the ML9042 device can cause device malfunction. In order
to avoid the device malfunction, power noise should be reduced by serial interfacing of the
microcontroller and the ML9042 device.
* Do not apply short-circuiting across output pins and across an output pin and an input/output
pin or the power supply pin in the output mode.
