Title: Semiconductor integrated circuit
Inventor: NARA TAKASHI
IPC: H03L7/16
Filed: 1992-02-03
Abstract: PURPOSE:To prevent the malfunctions caused when the output logics of plural output buffer circuits are switched all at once by providing an output delay circuit to scatter the switch timings of the output logics in a fixed range. CONSTITUTION:When a fixed or more number of inputs Yi1-Yin of output buffer circuits 4-1-4-n are switched all at once to 'H' from 'L' or vice verse in the same timing, the outputs Y1-Yn of the circuits 4-1-4-n undergo the delay control at the time when the output operating timings differ slightly from each other. Therefore, the outputs Y1-Yn ere never concentrated in a specific timing and scattered almost equally in a fixed time range to change to 'H' from 'L' and vice verse. As a result, a sudden change of the power voltage Vcc and a large transient noise caused by the sudden change of the Vcc can be suppressed. Thus, it is possible to prevent the malfunctions which are produced when the output logics of the circuits 4-1-4-n are switched all at once.
