‡
This is the bus-hold maximum dynamic current. It is the minimum overdrive current required to switch the input from one state to another.
§
This is the V
I
for A-port or control inputs.
¶
This is the V
I
for B port.
#
This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
