10-bit level shifting bus switch with 5-bit output enables
10. Dynamic characteristics
[1]
The propagation delay is the calculated RC time constant of the typical ON resistance of the switch and the specified load capacitance,
when driven by an ideal voltage source (zero output impedance).
[2]
tpd is the same as tPLH and tPHL.
ten is the same as tPZL and tPZH.
tdis is the same as tPLZ and tPHZ.
11. Waveforms
