Pin Name
Function
GND
Ground terminal for control logic and
current sink
SDI
Serial-data input to the Shift Register
CLK
Clock input terminal for data shift on
rising edge
Data strobe input terminal
LE(ED1)
Serial data is transferred to the
respective latch when LE(ED1) is high.
The data is latched when LE(ED1)
goes low.
Also, a control signal input for Error
Detection mode (See Timing Diagram)
5~20 OUT0 ~ OUT15 Constant current output terminals
Output enable terminal
When (active) low, the output drivers

are enabled; when high, all output
OE (ED2) drivers are turned OFF (blanked).
Also, a control signal input for Error
Detection mode (See Timing Diagram)
