A.C. TIMING CHARACTERISTICS
(TA = -40°C to +85°C, VDD = 3.3 V ± 8%)
Notes on Input Timing:
1. When a set-up time is specified between an input and a clock, the set-up time is
measured from the 50% point of the input to the 50% point of the clock.
2. When a hold time is specified between a clock and an input, the hold time is
measured from the 50% point of the clock to the 50% point of the input.
Notes on Output Timing:
1. Output timing is measured between the 50% point of the clock to the 50% point of
the output.
