TXS0108E: Expected maximum capacitive load

Section 7.3.3 of the TXS datasheet says:

The one-shot circuits have been designed to stay on for approximately 30ns. The maximum capacitance of the lumped load that can be driven also depends directly on the one-shot duration. With very heavy capacitive loads, the one-shot can time-out before the signal is driven fully to the positive rail. The one-shot duration has been set to best optimize trade-offs between dynamic I_CC, load driving capability, and maximum bit-rate considerations. Both PCB trace length and connectors add to the capacitance of the TXS0108E output. Therefore, TI recommends that this lumped-load capacitance is considered to avoid one-shot retriggering, bus contention, output signal oscillations, or other adverse system-level affects.

It does not mention a limit, but 70 pF is a good estimate. (With higher capacitances, the maximum data rate gets much lower; for slow protocols like I²C, this would not matter.)
