Pin Name
PD6325, PD6326, PD6335, PD6336
This pin is used to interface with the control IC
(ex. micro processor). Supply the voltage high
level of the control IC.
Control data input terminal. Data is read in syn-
chronization with the clocks input to the CLOCK
terminal.
Data read clock input terminal. The Data input
to the DATA IN terminal is read at the leading
edge of the clock.
This terminal is used to input Load signals after
inputting serial data. 12 bit data is read after
leading edge of a pulse input to the LOAD terminal.
Serial data output terminal. The final stage data
of 12 bit shift register appeares on this terminal
in synchronization with shift clock.
System ground.
