NOTES:
1. This parameter is determined by device characteristics but is not production
tested.
2. 3dv references the interpolated capacitance when the input and output signals
swith from 0V to 3V or from 3V to 0V.

NOTES:
1. At f = fmax, address inputs are cycling at the maximum read cycle of 1/tRC using the "AC Test Conditions" input levels of GND to 3V.
