Product Summary

The SA555DR is a precision monolithic timing circuit capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the SA555DR is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle may be independently controlled with two external resistors and a single external capacitor.
