Serial-Data Input. Data is loaded into the internal 16-bit shift register
on the rising edge of pin SCL.
Digit Drive Lines. Eight digit drive lines that sink current from the
display cathode.
Ground.
Load. Serial Data is loaded into the shift register while this pin is low.
The last 16 bits of serial data are latched on the rising edge of this pin.

Serial-Clock Input. 10MHz maximum rate. Data is shifted into the
internal shift register on the rising edge of this pin. Data is clocked out of
pin SDO on the rising edge of this pin.
Seven Segment and Decimal Point Drive Lines. 8 seven-segment
drives and decimal point drive that source current to the display.
Positive Supply Voltage. Connect to +2.7 to +5.5V supply.
Serial-Data Output. The data into pin SDI is valid at pin SDO 16 clock
cycles later. This pin is used to daisy-chain several devices and is never
high-impedance.
