Function
Description
POL
In
Polarity pin
When POL is low, VP and VN are swapped
functionally at the output pins level.
This signal is assumed static.
OUT1..OUT480
VP
Out
Power
Driver output pins
Power supply
The output voltage is either VP or VN for driving
the gate electrode, depending on the data stored
in the shift register. It is assumed that only up to 4
outputs are changing level simultaneously.
High voltage supply (eg +50 V)
DVDD
Power Power supply
Digital power supply
DGND
Power Power supply
Digital ground
VN
TEST
Power Power supply
In
Test pin
Negative supply
Test pin (must be grounded in application)
LENGTH
In
Nb of active
outputs
When LENGTH =0, enable 480 outputs
When LENGTH =1, enable 400 outputs
This signal is assumed static
JUSTIFY
Only applicable when LENGTH=1
In
Partial output
justify mode
When JUSTIFY = 0, use outputs 0 to 399
When JUSTIFY = 1, use outputs 80 to 479
This signal is assumed static.
In the pinout diagram:
● TEST is used to test the device.
