Notes:
(1)In case the output channel corresponding to the selected MUX channel is latched off while the relevant input is
low, CS pin delivers feedback according to OFF-State diagnostic.
(2)Example 1: FR = 1; IN0 = 0; OUT0 = L (latched); MUX channel = channel 0 diagnostic; CS = 0
(3)Example 2: FR = 1; IN0 = 0; OUT0 = latched, VOUT0 > VOL; MUX channel = channel 0 diagnostic; CS = VSENSEH
