Characteristics
**Not more than 1 output should be shorted at the same time. Duration of the short circuit should not exceed 30 s.
All voltages are referenced to VSS = 0 V (ground).
All characteristics are valid in the power supply voltage range and in the operating temperature range specified.
Dynamic measurements are based on a rise and fall time of
≤ 5 ns, measured between 10 % and 90 % of V
I, as well as
input levels of VIL = 0 V and VIH = 2.5 V. The timing reference level of all input and output signals is 1.5 V,
with the exception of the tdis-times and ten-times, in which cases transition is measured ±200 mV from steady-state voltage.
