ABSTRACT:
An EFL D-type latch having both true and complement output with a data input transistor and a bistable storage cell comprising first and second transistors, at least one of which is multi-emitter, connected such that the true output is connected to the collector of the first transistor of the storage cell and the complement output is connected to the collector of the data input transistor and the second transistor of the storage cell to take advantage of the phase inversion of the latter transistors depending upon which one of these transistors has current flowing therethrough. Also described is an EFL type complement output circuit connected as a D-type master-slave flip-flop, an RS latch, and a JK master-slave flip-flop using an RS master latch and a D-type slave latch. Also disclosed is a toggle flip-flop implemented with a D-type flip-flop to complete an EFL type logic family.
