STBY
Stays unselected. Not used for the HV2918 Analog Switch Evaluation Board.
3
MODE
Stays selected. Not used for the HV2918 Analog Switch Evaluation Board.
4
DIN
32-bit data entry boxes. Each bit in the boxes is related to each analog switch. If data
entry is ‘
1
’, the associated switch is set to on. If data entry is ‘
0
’, the associated switch
is set to off.
5
CLR
When this check box is selected, the CLR logic input is set to high and all the switches
of the HV2918 device are set to off. When cleared, the CLR logic input is set to low and
the 32 switches of HV2918 are set to ON/OFF states according to the DIN data entry.
