The MC100LVEL13 is a dual, fully differential 1:3 fanout buffer. The MC100EL13 is pin and functionally equivalent to the MC100LVEL13 but is specified for operation at the standard 100E ECL voltage supply. The Low Output-Output Skew of the device makes it ideal for distributing two different frequency synchronous signals.
The differential inputs have special circuitry which ensures device stability under open input conditions. When both differential inputs are left open the D input will pull down to V
, The Dbar input will bias around V
/2 and the Q output will go LOW.
