10-bit bus switch with output enable
10. Dynamic characteristics
[1]
All typical values are measured at Tamb =25 C and at nominal VCC.
[2]
The propagation delay is the calculated RC time constant of the on-state resistance of the switch and the load capacitance, when driven
by an ideal voltage source (zero output impedance).
[3]
tpd is the same as tPLH and tPHL.
[4]
ten is the same as tPZH and tPZL.
[5]
tdis is the same as tPHZ and tPLZ.
