SEMICONDUCTOR TECHNICAL DATA  
The MC100LVEL29 is a dual master–slave flip flop. The device  
features fully differential Data and Clock inputs as well as outputs. The  
MC100EL29 is pin and functionally equivalent to the MC100LVEL29 but  
is specified for operation at the standard 100E ECL voltage supply. A V  
BB  
output is provided for AC coupling, refer to the interfacing section of the  
ECLinPS Data Book (DL140) for more information on AC coupling ECL  
signals. Data enters the master latch when the clock is LOW and  
transfers to the slave upon a positive transition on the clock input.

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  
and the D input will bias around  
EE  
/2. The outputs will go to a defined state, however the state will be

random based on how the flip flop powers up.  
Both flip flops feature asynchronous, overriding Set and Reset inputs.  
Note that the Set and Reset inputs cannot both be HIGH simultaneously.
