(1) V
CCO
is the V
CC
associated with the output port.
(2) V
CCI
is the V
CC
associated with the input port.
(3) All typical values are at T
A
= 25°C.
(4) 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
IL
max.
(5) 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
CC
and then lowering it to V
IH
min.
(6) An external driver must source at least I
BHLO
to switch this node from low to high.
(7) An external driver must sink at least I
BHHO
to switch this node from high to low.
(8) For I/O ports, the parameter I
OZ
includes the input leakage current.
