[1] Typical values with VCC(A) = 1.1 V, VCC(B) = 5.0 V.
[2] VIL specification is for the falling edge seen by the port A input. VILc is for the static LOW levels seen by the port A input resulting in
port B output staying LOW.
[3] The port A current source has a typical value of about 1 mA, but varies with both VCC(A) and VCC(B). Below VCC(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 Ω defines the VOL.
[4] As long as the chip ground is common with the input ground reference the driver resistance may be as large as 120 Ω. However, ground
offset will rapidly decrease the maximum allowed driver resistance.
[5] Guaranteed by design.
