20 A.C. TIMING CHARACTERISTICS
(T_A = -40°C to +85°C, V_VDD = 3.3 V ± 0.3V, V_PCH = 2.5 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 time is measured between the 50% point of the clock to the 50% point
of the output.
