Characteristics are for clocked operation over the ranges of recommended operating temperature and supply voltage.
Typical figures are at 25°C and are for design aid only: not guaranteed and not subject to production testing.
* The difference between t
TSD
for TxA and TxB is not greater than 20 ns.
