(2) tsk(o) is the skew between outputs of a single device with all driving inputs connected together and the outputs switching in the same direction while driving identical loads. (3) tsk(pp) is the magnitude of the difference in propagation delay times between any terminals of different devices switching in the same direction while operating at identical supply voltages, temperature, input signals and loads. (4) The enable signal rate should be ≤ 43 Kbps 6.8 Switching Characteristics VCC1 and VCC2 at 3.3 V ± 10% (over recommended operating conditions unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT tPLH, tPHL Propagation delay time 22 36 66 ns See Figure 11 PWD(1) Pulse width distortion |tPHL – tPLH| 2.5 ns Same direction channels 3 tsk(o) (2) Channel-to-channel output skew time ns Opposite direction 16 channels tsk(pp) (3) Part-to-part skew time 27 ns tr Output signal rise time 3 ns See Figure 11 tf Output signal fall time 2 ns tPHZ Disable propagation delay, high-to-high impedance output 9 18 tPLZ Disable propagation delay, low-to-high impedance output 9 18 ISO733xC 9 18 Enable propagation delay, high impedance-to-high tPZH See Figure 12 ns output ISO733xFC 13000 24000(4) ISO733xC 13000 24000(4) Enable propagation delay, high impedance-to-low tPZL output ISO733xFC 9 18 tfs Fail-safe output delay time from input power loss See Figure 13 7 μs (1) Also known as pulse skew.
