Function

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.

D7 the data of the shift register appears on this

terminal. (Only µPD6325 and µPD6335)

D6 the data of the shift register appears on this

terminal.
