Data Input
Data is input on the SERIAL-IN terminal. Each 16 bit serial word includes an address (D15 ~ D8)
and data (D7 ~ D0). A low to high transition load command on the LOAD terminal loads the data
into the appropriate registers following the 16
Operation
Serial data is input on the DATA-IN terminal beginning with the most significant bit (MSB). Data
is clocked through the 16 bit shift register on the rising edge of the clock. A Low to High transi-
tion on the LOAD input following the 16
latch.
Expansion beyond four digits is possible through the use of a cascade connection from the
DATA-OUT terminal. The data-out lags data-in by one bit through the data-out terminal.
Each 16 bit word typically includes 8 address bits and 8 data bits. The first four data bits,
beginning with D15 (MSB) ~ D12 select the Action mode (see figure 1). These global com-
mands determine the overall function the device is to perform and includes Blank, Normal
Operation, Load Register, All On and Stand-by. Data bits D11~D8 select the particular register to
be loaded (see figure 2) should the load register function be selected. Data bits D7~D0 (LSB)
define the specific commands required to program the display and define the brightness setting
(duty cycle).

“x” indicates that data is required in this field to execute the function. “-” indicates that data in
this field is not required and not recognized.
