Stresses in excess of the absolute maximum ratings
can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the
device is not implied at these or any other conditions in
excess of those given in the operational sections of the
data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.

Notes:
x indicates output state unknown.
U1 and D1 outputs are sequential, i.e., they must be sequenced in
the order shown.
U2 and D2 outputs are combinational, i.e., they need only inputs to
obtain the desired output state.
