If the current is twice as high it will produce 2 volts etc. Currently the is not manufactured by any major chip companies possibly not by any companiesthus the should be treated as obsolete. Assume initially the output of the monostable is zero, the output of flip-flop Q bar is 1 so that the discharging transistor is on and voltage across capacitor is zero.

The timer IC is an integrated circuit chip used in a variety of datashretpulse generation, and oscillator applications. Archived from the original on January 9, The input signal should be connected through 555h series capacitor which then connects to the trigger and threshold pins. Otherwise the output low time will be greater than calculated above.

The new parent company inherits everything from datashet previous company then datasheets and chip logos are changed over a period of time to the new company. By using this site, you agree to the Terms of Use and Privacy Policy.

I mean, I don’t have a problem with downvoting the question, but please first provide me an datashet why?

Peter Mortensen 1, 3 14 As far as I can tell, you have a bad design and it may work with dstasheet chip but it certainly can’t be expected to work with different supplier’s chips. From Wikipedia, the free encyclopedia.


In general, when a circuit works with a device from one maker and not from another it is telling you is that your design is incorrectly using some feature of the device on the verge of the design characteristics. The ICM datasheet datasjeet that it datwsheet doesn’t require a “control” capacitor and in many cases does not require a decoupling capacitor across the power supply pins.

The can be used to provide time delays, as an oscillatorand as a flip-flop element. I’ve implemented a water level indicator using a timer.

I think the attitude was probably what led to any downvotes you may have gotten. You know what, I understand there is something bad with the system.

555 Timer IC

Other timers can have different specifications depending on the grade military, medical, etc. Control or Control Voltage: Some manufacturers’ parts will hold the output state to what it was when RESET is taken low, others will send the output either high or low.

Partial list of differences between and chips: It features two datadheet s in a 14 pin package.

Archived from the original on April 5, For bipolar timers, a decoupling capacitor is required because of current surges during output switching. The charging and discharging of capacitor depends on the time constant RC. Meanwhile N works I’ve checked with two ICs.

When bipolar timers are used in applications where the output drives a TTL input, a to pF decoupling capacitor may need to be added to prevent double triggering. You repeatedly argued with people saying “but it worked on one of them”.


Ashish Datasneet 1 7. I am getting downvoted here without really an explanation. The equation reduces to the expected 0.

The Apple II microcomputer used a quad timer in monostable or “one-shot” mode to interface up to four “game paddles” or two joysticks to the host computer. Camenzind proposed the development of a universal circuit based on the oscillator for PLLs, and asked that he would develop it alone, borrowing their equipment instead of having his pay cut in half.

Fix your design so the reset pin gets what it really needs, i. The reset pin is tied to V CC. One works, the other does not! A wide pulse represented the full-right joystick position, for example, while a narrow pulse represented the full-left joystick position.

Xatasheet design is flakey. The joystick potentiometer acted as a variable resistor in the RC network. A series resistor of ohms must be added to each R1 and R2 to limit peak current of the transistor within when R1 and R2 are at minimum level.

Thus datashdet, pulling the trigger momentarily to ground acts as a ‘set’ and transitions the output pin pin 3 to V CC high state. I didn’t know what? It has four reduced-functionality timers in a 16 pin package four complete timer circuits would have required 26 pins.

Retrieved 27 December The cycle repeats continuously. Depending on the manufacturer, the standard package includes 25 transistors2 diodes and 15 resistors on a silicon chip installed in an 8-pin dual in-line package DIP
