555 Bistable Multivibrator | Electronics Forum (Circuits, Projects …
2012年8月29日 · The most common 555 configurations are that of a Astable and Monostable Multivibrator. This shows how a 555 may be used as a Bistable Multivibrator. While a 555 has a Set/Reset flip flop built in (another type of Bistable Multivibrator) this circuit uses the concept of hysteresis to accomplish the same thing.

Cmos bistable momentary push button help | Electronics Forum …
2019年6月16日 · A 555 will work as a set/reset bistable circuit not readily as a toggle flip-flop. Here's a push-button controlled, bistable circuit using a CMOS CD4013 D-FlipFlop that includes a debounce function (R1-C2) for a mechanical push-button. The Out and Not_Out are complementary outputs. It can operate from a 3V to 15V supply. View attachment 118927
Latching-relay (single and dual-coil) simulation models
2016年7月26日 · In connection with this other thread, I developed LTspice simulation models respectively for single and dual-coil DPDT latching relays, based on data from various datasheets. I attach the .sub and .asy files here in case anyone else might find them useful or can suggest improvements. In use...
Driving a Bi-Stable solenoid - Electronics Forum (Circuits, Projects ...
2020年9月29日 · Hello all, My first project trying to use a bi-stable solenoid. The solenoid itself is not that high torque device so no high power requirements here. Solenoid specs: Operating voltage: 5VDC Coil resistance: 30Ω ~ 0.166mA CW/CCW pulse timing: 50ms/100ms (min/max) The device this is going to...
The versatile CD4093B Schmitt NAND IC - Electronics Forum …
2013年1月17日 · Schmitt logic gates such as in the CD4093 quad NAND gate IC are useful buiding blocks for various functions. The example functions shown here are oscillator, bistable, RS latch and monostable. I don't claim any originality for these, but thought it useful to bring them together for the benefit of newbies.
Push Button On/Off, Low Quiescent Power, High-Side MOSFET …
2015年10月15日 · Here is a simple, high-side power switch that requires only 1 N-MOSFET, 1 P-MOSFET, 3 resistors, 2 capacitors and a momentary PB for control. It is insensitive to the length of time the PB is pressed and also to any normal switch bounce. The OFF...
555 with 74HC595 - Electronics Forum (Circuits, Projects and ...
2019年3月16日 · hi everyone as a way of intro: I am new to this site and a relatively new electronics hobbyist. A quick summary of my circuit: I built a simple circuit with a 74HC595 w/ 8 output LEDs. I am looking to hook up the QH' back to the shift register's input pin. But, have not been able to get it...
Relays for relay counter - Electronics Forum (Circuits, Projects and ...
2010年5月14日 · And yes, dual coil relays are still available on the market. They are commonly called "bistable" or "latching" relays. The relays made by Ericsson shown in the counter drawing are not bistable. You could not use bistables in that circuit. FINDER applies another solution with a single coil which must be reversed to change switch condition. Boncuk
How to (appropriately) drive an ignition coil and/or a flyback?
2007年6月24日 · I would use a bistable multivibrator with the reset connected to the current sense comparator and bufferamp and the ouput to the gate of the MOSFET. This will effectively form a monostable vibrator with the coil and current sense resistor acting as the timing element.
