... CC resistor between the input(s) and V will flow if the input’s ESD protection starts conducting. The ISL32179E has the most flexible enable scheme. Its six enable pins allow for group, paired, or individual channel enable control. Figure 5 details the ISL32179E’s internal enable logic. To utilize a group enable function, connect all the ENx pins high, and handle the EN and EN pins as described in the previous paragraph ...

Thus, the logic device’s low V might not exceed the V OH powered DI or enable input. Connecting the V power supply of the logic device (as shown in Figure 6) reduces the DI and enable input switching points to values compatible with the logic device’ ...
