DescriptionThe MC100LVEL29 is a dual masterslave flip flop. The device features fully differential Data and Clock inputs as well as outputs. The MC100LVEL29 is pin and functionally equivalent to the MC100LVEL29 but is specified for operation at the standard 100E ECL voltage supply. A VBB 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 MC100LVEL29 stability under open input conditions. When both differential inputs are left open the D input will pull down to VEE and the D input will bias around VCC /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 MC100LVEL29 feature asynchronous, overriding Set and Reset inputs. Note that the Set and Reset inputs cannot both be HIGH simultaneously.
