NOTES:
1.
AC Electrical Characteristics specified at ‘AC Test Conditions’ levels.
2.
Active output to High-Z and High-Z to output active tests specified for a
±
500 mV transition from steady state levels into the test load. The test
load has 5 pF capacitances.
3.
Guaranteed by design but not tested.
