Title: Selective signal circuit
Inventor: IKEMOTO TAKATOMO
IPC: H03K17/00
Filed: 1990-01-12
Abstract: PURPOSE:To shorten the rising time and to accelerate the signal processing by providing a means restoring a part in common connection to a signal line via a transistor(TR) switch to a prescribed reference level in an LSI circuit applying digital signal processing especially. CONSTITUTION:When a clock is at, e.g. an L level, TRs M1-M4 and a TR Q1 are turned off. Thus, wired connection part W1 is charged to a level V1 through the turning on of a TR Q2. A clock changes to an H level and the TR M1 is turned on and an H level is inputted to an input signal line D0, the part W1 is charged from the level V1 to the level VH. Moreover, when an L level is inputted to the input signal line D0, the W1 is discharged from the level V1 to the level VL. Thus, since the wired connection part of the TR switch is restored quickly to a prescribed reference level, the time to select and output a signal is shortened.
