Abstract
Improved precharge circuit for a dynamic circuit having N, spaced apart, outputs; where N is an integer greater than 2. The conduction path of a precharge transistor is connected between each pair of outputs, whereby (N-1) precharge transistors are connected end-to-end between the N output points. At least one additional precharge transistor is connected between one of the N outputs and a precharge potential point. A common conductor interconnects the control electrodes of all the precharge transistors for, selectively, turning them on concurrently and distributing the precharge potential to all of the N outputs. The end-to-end connection of the N-1 transistors enables the conduction paths of the N-1 transistors and the common conductor to be formed orthogonally to output line conductors connected to the N outputs, thereby enabling the manufacture of a dense and compact circuit.
