SEMICONDUCTOR TECHNICAL DATA

Dual Differential Data and Clock

D Flip-Flop With Set and Reset

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.

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.

Note that the Set and Reset inputs cannot both be HIGH simultaneously.
