Terminal Description
Pin No.
Pin Name
Function
1
GND
Ground terminal for control logic and current sink
2
SDI
Serial-data input to the Shift Register
3
CLK
Clock input terminal for data shift on rising edge
4
LE(CA1)
Data strobe input terminal
Serial data is transferred to the respective latch
when LE(CA1) is high. The data is latched when
LE(CA1) goes low.
Also, a control signal input for Current Adjust
mode (See Timing Diagram)

OUT0 ~ OUT15 Constant current output terminals
21
OE (CA2)
Output enable terminal
When (active) low, the output drivers are enabled;
when high, all output drivers are turned OFF
(blanked).
Also, a second control signal input for Current
Adjust mode (See Timing Diagram)
