(LV)PECL, (LV)ECL compatible 2:1 mux input signal select: When IN_SEL is LOW, the
IN0 input pair is selected. When IN_SEL is HIGH, the IN1 input pair is selected. Includes a
75k
pull-down. Default state is LOW and IN0 is selected.
(LV)PECL, (LV)ECL, HSTL clock or data inputs.
Internal 75k
pull-down resistors on IN0, IN1. Internal 75k
pull-up and 75k
pull-down
resistors on /IN0, /IN1.
/IN0, /IN1 default condition is V
