Notes:

(1)In case the output channel corresponding to the selected MUX channel is latched off while the

relevant input is low, Multisense pin delivers feedback according to OFF-State diagnostic.

Example 1: FR = 1; IN0 = 0; OUT0 = L (latched); MUX channel = channel 0 diagnostic; Mutisense = 0.

Example 2: FR = 1; IN0 = 0; OUT0 = latched, VOUT0 > VOL; MUX channel = channel 0 diagnostic;

Mutisense = VSENSEH
