PARAMETER MEASUREMENT INFORMATION
NOTES: A. C 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.
C. All input pulses are supplied by generators have the following characteristics: PRR 10 MHz, Z = 50 , slew rate 1 V/ns.
D. The outputs are measured one at a time, with one transition per measurement.
E. t and t are the same as t .
F. t and t are the same as t .
G. t and t are the same as t .
H. All parameters and waveforms are not applicable to all devices.
