** INITIAL DELAY &CUMULATIVE TOLERANCES: "Error" Tolerance is for ProgrammedDelays Referencedto Initial Delay, Setting"000."
For example, the setting "111" delay of PECL3-2 is 14.0 ± 0.8 ns ref. to "000," and 17.0 ± 1.3 ns referenced to the input,
and the setting "111" delay of 3PECLH-2 is 14.0 ± 0.8 ns ref. to "000," and 15.5 ± 1.3 ns referenced to the input.
INPUT LOADING: Input, Pin 6, internally connected to eight ECL
gateinputsterminatedby Theveninequivalent of 100Ohmsto-2V.
