Description 555 Timer, a series of highly stable high-precision timing circuits from Texas Instruments, used for accurate delay or timing pulses. These timers can operate in either monostable (single trigger) or non-stationary oscillator mode, with a calculation period of less than microseconds to a few minutes. In addition to the original bipolar model, low-power CMOS and LinCMOS variants are also available. These devices support longer timing cycles and significantly reduce power consumption. This series includes single (551, 555) and dual (552, 556) timer versions. ###Timer/Timer Generator
