Notes:
1.VPP rise time (dv/dt) should be less than 50V/µS.
2.Power-up sequence should be the following:
A) Connect ground;
B) Apply V ;
PP
C) Apply VCC;
D) Apply VLL;
E) Set all inputs to a known state. Power-down sequence should be the reverse of the above.

Notes:
1. X indicates “Don’t Care” input state (L or H).
2. The output threshold is internally tested for each PD(N) output; the pass condition occurs when OE = H and:
A) PD(N) driving high with output > VTH (MAX), or may occurs if PD(N) driving high and output > VTH (MIN) and < VTL (MAX).
OR
B) PD(N) driving Low with output < VTH (MIN), or may occur if PD(N) driving low and output < VTH (MAX) and < VTL (MIN).
The fail condition occurs when OE = H and conditions for “pass” are not satisfied.
3. Fault output = VFL indicates a fault has been detected in at least one of the PD(N) output loads when OE = H. All other outputs shall function 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 VFH, and the fault latch is reset. If the fault condition persists, the fault response repeats each
time the OE input is set to H.
4. H>L indicates falling edge (H to L).
5. HI-Z indicates no current is sourced to output PD(N).
6. P/F indicates “Pass” or “Fail” fault threshold conditions.
