Features

• A series of highly stable precision timing circuits for accurate time delay or timing pulse generation.
• This timer can operate in mono-stable (one-shot) or non-stable (oscillator) mode with timing periods ranging from less than one microsecond to several minutes.
• In addition to the original bipolar type, low-power CMOS and LinCMOS types are also available.
• These devices support longer timing periods and can significantly reduce power consumption.
• Both single type (551, 555) and dual type (552, 556) timers are available.
