![]() ![]() At the application of an interrupt, the timer output turns low (0). ![]() If the stable output is set at high (1), the output of the timer is high (1). The stable state can be chosen as either high or low by the user. This configuration consists of one stable and one unstable state. This character of unstable output is used as a clock or square wave output for many applications.Īlso Check: 555 Timer Astable Circuit Calculator Monostable Mode So the output will be swinging between high and low. This means there will be no stable level of output. ![]() The 555 timer IC generally operates in 3 modes: Also, the maximum power dissipation per package is 600 mW, and its trigger pulse and reset inputs have logic compatibility.The duty cycle of the timer is adjustable.It has a temperature stability of 50 parts per million (ppm) per degree Celsius change in temperature which is equivalent to 0.005 %/ ☌. ![]() The output pin of a 555 timer can drive a transistor-transistor logic (TTL) due to its high current output.The external components should be selected properly so that the timing intervals can be made into several minutes along with the frequencies exceeding several hundred kilohertz.Sinking or sourcing 200 mA of load current.It operates from a wide range of power ranging from +5 Volts to +18 Volts supply voltage.Some of the major features of the 555 timers would be, A 555 timer works as a flip-flop or as a multi-vibrator, it has a particular set of configurations. Positive supply voltage, which is usually between 3 and 15 V depending on the variation.ĥ55 timer is used in almost every electronic circuit today. ![]()
