NOTES:

1. See Test Conditions under TEST CIRCUITS AND WAVEFORMS.

2. This parameter is guaranteed but not production tested.

3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the

order of 0.2ns at C^L= 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the system. Propagation

delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.

4. Minimums are guaranteed but not production tested.

5. Maximum toggle frequency for Sx or E control input (pass voltage > VCC, VIN = 5V, RLOAD ≥ 1MΩ, no CLOAD).
