AC CHARACTERISTICS I
(AC operating conditions unless otherwise noted)
Note :
1.Assume tR / tF (input rise and fall time ) is 1ns
If tR & tF > 1ns, then [(tR+tF)/2-1]ns should be added to the parameter
2.Access times to be measured with input signals of 1v/ns edge rate, from 0.8v to 2.0v
If tR > 1ns, then (tR/2-0.5)ns should be added to the parameter
