Description
D0~D3
I
CMOS IN
Pull-high
or floating
Data inputs for the parallel mode
When the IC is operating in the serial mode, the data input
terminals (D0~D3) are included with a pull-high resistor. When
the IC is operating in the parallel mode, these pins become
floating.

I
CMOS IN
Operation mode selection input
S/P=“H”: Parallel mode

CLK
I
CMOS IN
Pull-high
or floating
Data synchronous clock input for the serial mode
When the IC is operating in the parallel mode, the input
terminal (CLK ) is included with a pull-high resistor. When the
IC is operating in the serial mode, this pin becomes floating.

Data input terminal for the serial mode
When the IC is operating in the parallel mode, the input terminal
(DATA) is included with a pull-high resistor. When the IC is
operating in the serial mode, this pin becomes floating.
