Typical values with V

= 1.1 V, V
CC(B)
= 5.0 V.
V
IL
specification is for the falling edge seen by the port A input. V
ILc
is for the static LOW levels seen by the port A input resulting in
port B output staying LOW.
[2]
[3]
The port A current source has a typical value of about 1 mA, but varies with both V
CC(A)
and V
CC(B)
. Below V
CC(A)
of about 0.7 V the
port A current source current drops to 0 mA. The current source current dropping across the internal pull-down driver resistance of
about 200
defines the V
OL
.
As long as the chip ground is common with the input ground reference the driver resistance may be as large as 120
. However, ground
offset will rapidly decrease the maximum allowed driver resistance.
