CUMULATIVE TOLERANCES:

"Error" Tolerance is for Programmed Delays

Referenced to 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.

ENABLE input, Pin 2, is active low. Output will be disabled ( low) when " E " is high.

INPUT LOADING: Input, Pin 6, internally connected to eight ECL gate inputs

terminated by Thevenin equivalent of 100 Ohms to -2V.
