Abstract
For preventing an input signal supplied to an input terminal (A) from directly affecting an inverted signal derived at a node (15), an inverter stage of an inverter-buffer circuit composed of MOS transistors comprises two additional partial inverter stages (Q.sub.6 -Q.sub.5 and Q.sub.7 -Q.sub.8) between a buffer stage (Q.sub.3 -Q.sub.4) and a conventional inverter stage (Q.sub.1 -Q.sub.2) that serves now as an input-side partial inverter stage. The buffer stage favorably comprises an additional MOS transistor (Q.sub.9) having a gate connected directly to the node in order to achieve a short switching delay.
