The logic levels are differently defined for positive or

negative logic (see Fig.9). It should be noted that positive

logic levels are inverted if a negative supply voltage is

used.

Outputs as a function of switch input pins S1, S2,

See Tables 1, 2, 3 and 4.

The default value for the switch input pins S1, S2, INV1

and INV2 if not connected, is zero.
