7 / 26 page  ISO7142CC-Q1 www.ti.com SLLSER5 – DECEMBER 2015 6.12 Switching Characteristics—5-V Supply VCC1 and VCC2 at 5 V ± 10% (over recommended operating conditions unless otherwise noted.) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT tPLH, tPHL Propagation delay time See Figure 8 15 21 38 ns PWD(1) Pulse width distortion |tPHL – tPLH| See Figure 8 3.5 ns Same-direction channels 1.5 Channel-to-channel output skew tsk(o) (2) ns time Opposite-direction channels 6.5 tsk(pp) (3) Part-to-part skew time 14 ns tr Output signal rise time See Figure 8 2.5 ns tf Output signal fall time See Figure 8 2.1 ns Disable propagation delay, tPHZ, tPLZ high/low-to-high impedance See Figure 9 7 12 ns output Enable propagation delay, high tPZH See Figure 9 6 12 ns impedance-to-high output Enable propagation delay, high tPZL See Figure 9 12 23 us impedance-to-low output Fail-safe output delay time from tfs See Figure 10 8 μs input data or power loss tGR Input glitch rejection time 9.5 ns (1) Also known as pulse skew (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. 6.13 Switching Characteristics—3.3-V Supply 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 See Figure 8 16 25 46 ns Pulse width distortion |tPHL – PWD(1) See Figure 8 3 ns tPLH| Same-direction Channels 2 Channel-to-channel output tsk(o) (2) ns skew time Opposite-direction Channels 6.5 tsk(pp) (3) Part-to-part skew time 21 ns tr Output signal rise time See Figure 8 3 ns tf Output signal fall time See Figure 8 2.5 ns Disable propagation delay, from tPHZ, tPLZ high/low to high-impedance See Figure 9 9 14 ns output Enable propagation delay, from tPZH See Figure 9 9 17 ns high-impedance to high output Enable propagation delay, from tPZL See Figure 9 12 24 us high-impedance to low output Fail-safe output delay time from tfs See Figure 10 7 μs input data or power loss tGR Input glitch rejection time 11 ns (1) Also known as pulse skew (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.
