Specifications
2.5 AC Electrical Characteristics
The timing waveforms shown in the AC electrical characteristics section are tested with a VIL maximum of 0.3 V
and a VIH minimum of 2.4 V for all pins except EXTAL, which is tested using the input levels shown in Note 6 of
Table 2-3. AC timing specifications, which are referenced to a device input signal, are measured in production with
respect to the 50 percent point of the respective input signal’s transition.
Note:
Although the minimum value for the frequency of EXTAL is 0 MHz, the device AC test conditions are 15
MHz and rated speed.
All specifications for the high impedance state are guaranteed by design.
