See Section 6.8 for t_r and t_f specifications and conditions.

Figure 6-4 Test Load Circuit for Output Propagation Measurement

For output timing analysis, the tester pin electronics and its transmission line effects must be taken into account. System designers must use IBIS or other simulation tools to correlate the timing reference load to a system environment.
