(1)

Over recommended operating free-air temperature range TA, AVDD = 5V, and DVDD = 2.7V to 5.5V, unless otherwise noted.

(2)

All input signals are specified with tR = tF = 1.5ns (10% to 90% of DVDD) and timed from a voltage level of (VIL + VIH)/2.

(3)

Refer to CS signal or RD, whichever occurs first.
