77 / 110 page  77/110 PSD813F1 DC AND AC PARAMETERS This section summarizes the operating and mea- surement conditions, and the DC and AC charac- teristics of the device. The parameters in the DC and AC Characteristic tables that follow are de- rived from tests performed under the Measure- ment Conditions summarized in the relevant tables. Designers should check that the operating conditions in their circuit match the measurement conditions when relying on the quoted parame- ters. Table 39. Operating Conditions (5V devices) Table 40. Operating Conditions (3V devices) Table 41. AC Signal Letters for PLD Timings Note: Example: tAVLX = Time from Address Valid to ALE Invalid. Table 42.
