Delays that can occur after ENABLE and/or idle times have passed.
Guaranteed by design, not production tested.
I
Input pull-up voltage should not exceed power supply voltage in operating mode because the rise time accelerator will clamp the voltage
to the positive supply rail.
The connection circuitry always regulates its output to a higher voltage than its input. The magnitude of this offset voltage as a function
of the pull-up resistor and V
