NOTES:
1. Input leakage currents include hi-Z output leakage for all bi-directional buffers with tri-state outputs.
2. This is a recommendation, not an absolute requirement. The actual value should be provided with the
component data sheet.

NOTES:
1. The overshoot and undershoot voltage duration is <=3ns with no input clamp diodes
2. The VDDQ and VSSQ are the operating parameters (not absolute max. parameters)
The refresh rate for all devices is assumed at a maximum of 15.6us per row per
the table below.
