(1) All typical values are at V
CC
= 3.3 V, T
A
= 25°C.
(2) For I/O ports, the parameters I
OZH
and I
OZL
include the input leakage current.
(3) 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, then raising it to V
IL
max.
(4) 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
, then lowering it to V
IH
min.
(5) An external driver must source at least I
BHLO
to switch this node from low to high.
(6) An external driver must sink at least I
BHHO
to switch this node from high to low.
(7) High-impedance state during power up or power down
(8) This is the increase in supply current for each input that is at the specified TTL voltage level, rather than V
CC
or GND.
