Pin 4 VDD should be filtered with 0.1 μF capacitor.

Not including current through pull-up resistor on EN pin (if configured).

Includes frequency variations due to initial tolerance, temp. and power supply voltage.

Input waveform must be monotonic with rise/fall time < 10 ms

Output Disable time takes up to two periods of the output waveform + 200 ns.

For parts configured with OE, not Standby.

Output is enabled if pad is floated or not connected.

Time to reach 90% of target VDD. Power ramp rise must be monotonic.
