PUSHBUTTON ONESHOT AND LATCH
This circuit uses a single IC to convert a noisy pushbutton switch signal into a
clean pulse or a sustained push on-push off signal. It can operate from 3v to 18v.

One-shot circuit is Programmable - 21-Dec-01 Issue of EDN
Figure 1 shows how to digitally program the on-time of a one-shot
multivibrator circuit. More and more, the Internet is playing a role in
control operations in industrial and R&D endeavors and in household
appliances. One-shot circuits are popular choices for the on/off control
circuitry.…. [Design Idea by J Jayapandian, IGCAR, Tamil Nadu, India] |
One-shot provides frequency discrimination - 1-May-03 Issue of
EDN You use a frequency discriminator to compare one signal
frequency with another one. A functional feature, retriggering, of a
monostable, one-shot 74xx123 multivibrator can yield frequency
discrimination. Figure 1 shows a frequency discriminator that determines
the relation of input-pulse frequency to a reference frequency. [Design

Simple Electronic 'Lock' - There are six (or more) push switches.
To 'unlock' you must press all the correct ones at the same time, but not
press any of the cancel switches. Pressing just one cancel switch will
prevent the circuit unlocking. When the circuit unlocks it actually just
turns on an LED for about one second, but it is intended to be adapted to
turn on a relay which could be used to switch on another circuit. Most
relays cost about £2 to £3 extra. [Designed by John Hewes] |

Slow OpAmp Makes Fast Multivibrator - 01/01/98 EDN-Design Ideas ....A classic
one-shot multivibrator using an op Amp (Figure 1a) needs a relatively long-duration
triggering pulse, even though the circuit is in theory a slope-triggered
configuration. This limitation can be a problem when you want to use a "spare"
op Amp from a dual or quad package (LM324, LM358, LM6482, or LT1013, for example)
triggered. [Design Idea by Lukasz Sliwczynski, University of Mining and Metallurgy,
Krakow, Poland ] |
