The MC10/100EP29 is a dual master-slave flip flop. The device features fully differential Data and Clock inputs as well as outputs. The MC10/100EP29 is functionally equivalent to the MC10/100EL29. 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 Dbar input will pull down to V
and the Dbar input will bias around V
/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.
The V
pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to V
as a switching reference voltage. V
may also rebias AC coupled inputs. When used, decouple V
and V
via a 0.01uF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, V
should be left open.
