Hi Martin, Here's the pin assignment: 1 VB Substrate bias voltage. 2 H1 High end of resistor. 3 L1 Low end of resistor. 4 W1 Wiper terminal. 5 ~RST Serial port reset input. 6 CLK Serial port clock input. 7 GND 8 DQ Serial port data input. 9 Cout Cascade port output. 10 L0 Low end of resistor. 11 H0 High end of resistor. 12 W0 Wiper terminal. 13 Sout Stacked configuration output. 14 Vcc +5V supply.
Hope this helps. I can send you more details if needed.
