Integrated circuit module for clock pulse switching - has shift register in circular configuration, and OR-gate in front of each memory element

摘要

The switching integrated circuit contains a shift register ring of register cells (Z1-n). Each cell contains a flip-flop (Dy) coupled via an OR-gate (Gy) either directly, or via a resetting input of a series connected further OR-gate (Oy) to all other register cells, with the exception of that preceding in a shift direction. The feedback results in a H-condition only in one register cell in the shift register ring. A clock pulse monitor (2) starts the shift register ring on starting operation, then is renewed when no register cell transmits a control signal (St), due to failure. The clock pulse switching is carried out with clock pulses of identical phase spacing and frequency to one with an advanced clock pulse phase. USE/ADVANTAGE - Digital signal multiplexers, with high switching velocities and simple use. (8pp Dwg.No.4/6)
