IN558

IN555, IN556, IN558 CMOS GENERAL PURPOSE TIMER General Description The IN555, IN556, IN558 are CMOS RC timers providing significantly improved performance over the standard SE/NE555/556/558 and 355 timers, while at the same time being direct replacements for those devices in most applications. Improved parameters include low supply current, wide operating supply voltage range, low THRESHOLD, TRIGGER, and RESET currents, no crowbarring of the supply current during output transitions, higher frequency performance and no requirement to decouple CONTROL VOLTAGE for stable operation. Specifically, the IN555/556/558 are stable controllers capable of producing accurate time delays of frequencies. The IN556 is a dual IN555, with the two timers operating independently of each other, sharing only VCC and GND. The 558 Quad Timers are monolithic timing devices can be used in a monostable mode to produce accurate time delays.
