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
4. Minimums are guaranteed but not production tested.
5. Maximum toggle frequency for OEx control input (pass voltage > V
