Terminal Description
Block Diagram
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
Data strobe input terminal
Serial data is transferred to the output latch when /LE is high. The data is latched when
/LE goes low.
5~20 OUT0~OUT15 Constant current output terminals
21
/OE
Output enable terminal
When (active) low, the output drivers are enabled; when high, all output drivers are turned OFF (blanked).
22 SDO Serial-data output to the following SDI of next driver IC
23 R-EXT Input terminal used to connect an external resistor for setting up output current for all output channels
