(2) This is the bus-hold maximum dynamic current. It is the minimum overdrive current required to switch the input from one state to
another.
(3) On products compliant to MIL-PRF-38535, this parameter is not production tested.
(4) This is the increase in supply current for each input that is at the specified TTL voltage level, rather than V
CC
or GND.
