tdis Disable Time (of a 3-State or Open-Collector Output)
JEDEC – no definition offered
TI – The propagation time between the specified reference points on the input and output voltage waveforms, with the output changing from either of the defined active levels (high or low) to the high-impedance (off) state.
NOTE: For 3-state outputs, tdis = tPHZ or tPLZ. Open-collector outputs change only if they are low at the time of disabling, so tdis = tPLH.
