Parameter Measurement Information (VDD = 1.8V - 3.6V)
Setup, Hold, and Release Timing
Pulse Width
Switch Position
Propagaton Delay
Enable Disable Timing
Notes:
A. CL includes probe and jig capacitance.
B. Waveform 1 is for an output with internal conditions
such that the output is LOW except when disabled by
the output control.
Waveform 2 is for an output with internal conditions
such that the output is HIGH except when disabled by
the output control.
All input pulses are supplied by generators having the
following characteristics: PRR
≤ 10 MHz, ZO = 50Ω,
tr
≤ 2ns, t
f
≤ 2ns, measured from 10% to 90%, unless
otherwise specified.
The outputs are measured one at a time with one
transition per measurement.
