PARAMETER MEASUREMENT INFORMATION
(Propagation Delays, Setup and Hold Times, and Pulse Width)
A. C
L
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 having the following characteristics: PRR ≤ 10 MHz, Z
O
= 50 Ω, for
propagation delays t
r
/t
f
= 3 ns, for setup and hold times and pulse width t
r
/t
f
= 1.2 ns.
D. The outputs are measured one at a time, with one transition per measurement.
E. t
PLH
and t
PHL
are the same as t
pd
.
F. All parameters and waveforms are not applicable to all devices.
