Test Circuits and Switching Waveforms
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 follow
ing characteristics: PRR
≤ 10 MHz, ZO = 50Ω, tR ≤ 2ns,
tF
≤ 2ns, measured from 10% to 90%, unless
otherwise specified.
The outputs are measured one at a time with one transition per
measurement.
