X indicates “Don’t Care” input state (L or H).
The output threshold is internally tested for each P
FAULT output = V
normally when a fault condition has been detected for one of the outputs. The FAULT output shall remain in the low state, regardless of the state
of the output which initiated the fault status, until the next falling edge of OE. Whenever OE = L, the FAULT output is forced to V
latch is reset. If the fault condition persists, the fault response repeats each time the OE input is set to H.
H>L indicates falling edge (H to L).
HI-Z indicates no current is sourced to output P
P/F indicates “Pass” or “Fail” fault threshold conditions.
