Philips Semiconductors Linear ProductsProduct specificationDual timerNE/SA/SE556/NE556-1DESCRIPTIONPIN CONFIGURATIONBoth the 556 and 556-1 Dual Monolithic timing circuits are highlystable controllers capable of producing accurate time delays orD, F, N Packagesoscillation. The 556 and 556-1 are a dual 555. Timing is provided byan external resistor and capacitor for each timing function. The twoDISCHARGE114VCCtimers operate independently of each other, sharing only VCC andground. The circuits may be triggered and reset on fallingTHRESHOLD213DISCHARGEwaveforms.

When it is timed out (determined by 1.1R1C1) the secondpossible to obtain sequential timing. By connecting the output of thehalf begins. Its duration is determined by 1.1R2C2.first half to the input of the second half via a 0.001μF couplingcapacitor sequential timing may be obtained.
