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 16th clock pulse. 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 transition on the LOAD input following the 16th (LSB) bit latches the 16 bit word into the 16 bit D-type 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 commands 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). Figure 1.

Blank - Constant current segment drivers are off resulting in an all segments off condition. Data D15 ~ D12 are 0. D11~D0 are not relevent in blank mode. 2. Normal (Operation) - Instructs device to display data loaded during previous steps. D11~ D0 are not relevent in the Normal Operation mode. 3. Load Register - Directs the device to recognize and load D11~ D0. In this mode D11 ~ D8 determines the specific register to be loaded (see figure 2) and D7 ~ D0 serves as the actual data to be loaded for programming the brightness (duty cycle) or the particular digit. 4. All On - All constant current segment drivers are on resulting in an all segments illuminated condition. D11 ~ D0 are not relevent in this mode. 5. Stand By - All display segments off condition. The Stand-By command turns off all internal bias currents and serves as a low power consumption mode (
