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 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 device 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 feature asynchronous, overriding Set and Reset inputs. Note that the Set and Reset inputs cannot both be HIGH simultaneously.
This document provides technical specifications for the Motorola MC100LVEL29 and MC100EL29, which are dual master-slave flip-flops featuring fully differential data and clock inputs and outputs. The MC100LVEL29 is specified for 1100MHz operation, while the MC100EL29 is pin and functionally equivalent but specified for standard 100E ECL voltage supply.
