The bus-hold circuit can sink at least the minimum low sustaining current at V
IL
max. I
BHL
should be measured after lowering V
IN
to GND
and then raising it to V
max.
The bus-hold circuit can source at least the minimum high sustaining current at V
IH
min. I
BHH
should be measured after raising V
IN
to V
and then lowering it to V

An external driver must source at least I
BHLO
to switch this node from low to high.
An external driver must sink at least I
to switch this node from high to low.
For I/O ports, the parameter I
OZ
includes the input leakage current.
