Specifications
2.5 AC Electrical Characteristics
The timing waveforms shown in the AC electrical characteristics section are tested with a V
and a V
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
