High voltage outputs.
High voltage push-pull outputs, which, depending on controlling low voltage data, can drive
loads either to a GND, or to V

Serial data output
Data output for cascading to the data input of the next device.
19 N/C
No connect.
20 N/C
21 Polarity ---
22 CLK
Data shift register clock.
Input are shifted into the shift register on the positive edge of the clock.
23 GND Logic and high voltage ground.
24 VPP High voltage power rail.
25 VDD Low voltage logic power rail.
26 Latch Enable
Latch enable input.
When LE is high, shift register data is transferred into a data latch. When LE is low, data is
latched, and new data can be clocked into the shift register.
27 Data In
Serial data input.
Data needs to be present before each rising edge of the clock.
