3.3V / 5V ECL Dual
Differential Data and Clock
D Flip-Flop With Set and
Reset
Description
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 D input will pull down to V
EE
and the D input will
bias around V
CC
/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
BB
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
BB
as a switching reference voltage.
V
BB
may also rebias AC coupled inputs. When used, decouple V
BB
and V
CC
via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, V
BB
should be left open.
The 100 Series contains temperature compensation.
