AC Electrical Characteristics
Voltages are with respect to ground (VSS) unless otherwise stated.
† Timing is over recommended temperature & power supply voltages.
‡ Typical figures are at 25 C and are for design aid only: not guaranteed and not subject to production testing.
* High Impedance is measured by pulling to the appropriate rail with R
