Overview

A range of highly stable precision timing circuits for the generation of accurate time delays or timing pulses. These timers can be operated in monostable (one-shot) or astable (oscillator) mode with timing periods ranging from less than a microsecond to several minutes. In addition to the original bipolar version, low-power CMOS and LinCMOS variants are also available. These devices are capable of longer timing periods and offering a significant reduction in power consumption. The range includes both single (551, 555) and dual (552, 556) versions of the timer.

DescriptionThe NE556, SA556 and SE556 dual monolithic timing circuits are highly stable controllers capable of producing accurate time delays or oscillation. In the time delay mode of operation, the time is precisely controlled by one externalresistor and capacitor. For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with twoexternal resistors and one capacitor.The circuits may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200 mA.■ Low turn-off time■ Maximum operating frequency greater than 500 kHz■ Timing from microseconds to hours■ Operates in both astable and monostable modes■ Output can source or sink up to 200 mA■ Adjustable duty cycle■ TTL compatible■ Temperature stability of 0.005% per °C
