Title: Delay circuit
Inventor: SASAKI SUSUMU
IPC: H03K5/13
Filed: 1984-12-24
Abstract: PURPOSE:To attain a high-speed operating function with a monostable multivibrator of a low-speed operation by changing the slow rise and fall of the monostable multivibrator to the sharp rise and fall with use of a comparator having a high-speed operation and ignoring the rise and fall times excepting the delay time that is produced by the monostable multivibrator itself. CONSTITUTION:An output 1 having the gentle rise and fall is obtained from a monostable multivibrator 2 which is driven by a high-speed rectangular wave applied from a terminal IN. The output 1 is applied to a comparator 8 which has the threshold voltage Vs and works at a high speed. Thus an output 2 having the sharp rise and fall is delivered through a terminal OUT. That is, the time delay due to the rise and fall times excepting the pulse width (delay time) is reduced down to such a level that can be ignored. Thus a logical error can be prevented with a high-speed IC connected to the next stage.
