Serial data input pin
Shift clock input pin
Serial data input from the DI pin are inputted to the internal shift
register at the rising edge of the CLK signal.
Load strobe input pin
When this pin is “High”, the shift register contents are loaded into
the decoder and 8-bit register.
Serial data output pin
The serial data in the shift register are outputted from this pin.
This pin allows a cascade connection.
Ground
No connection
