Table 4. Dynamic Electrical Characteristics

Characteristics noted under conditions 4.75 V ≤ VDD ≤ 5.25 V, - 40°C ≤ TJ ≤ 150°C, GND = 0 V unless otherwise noted.

Typical values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.

Notes

15. Maximum specified time for the 33976 is the minimum guaranteed time needed from the microcontroller.

16. The minimum and maximum value will vary proportionally to the internal clock tolerance. These numbers are based on an ideally

calibrated clock frequency of 1.0 MHz. These are not 100 percent tested.
