Dual 1:3 Fanout Buffer

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 VEE, The D input will bias around VCC/2

and the Q output will go LOW.
