When logic ‘0’, SD3 goes to the open state which deactivates the internal relay
driver 4, RD4 output goes to the open state.
When logic ‘0’ SD2 goes to AGND which deactivates the internal relay driver 3,
RD3 output goes to the open state.
A logic ‘0’, SD1 goes to AGND which deactivates the internal relay driver 2, RD2
output goes to the open state.
A logic ‘1’, SD1 goes to V
DD
which activates the internal relay driver 2, RD2 output
goes to RGND.
A logic ‘0’, SD0 goes to AGND which deactivates the internal relay driver 1, RD1
output goes to the open state.
A logic ‘1’, SD0 goes to V
DD
which activates the internal driver 1, RD1 output goes
to RGND.
