† Characteristics are over recommended operating conditions unless otherwise stated.
‡ Typical figures are at 25°C and are for design aid only: not guaranteed and not subject to production testing.
* Note 1: High Impedance is measured by pulling to the appropriate rail with RL, with timing corrected to cancel the time taken to discharge CL.
