DESCRIPTION
PIN CONFIGURATION
Both the 556 and 556-1 Dual Monolithic timing circuits are highly
stable controllers capable of producing accurate time delays or
oscillation. The 556 and 556-1 are a dual 555. Timing is provided by
an external resistor and capacitor for each timing function. The two

R=3.4MΩ.
4. Matching characteristics refer to the difference between performance characteristics for each timer section in the monostable mode.
5. Specified with trigger input high. In order to guarantee reset the voltage at reset pin must be less than or equal to 0.4V. To disable reset
function, the voltage at reset pin has to be greater than 1V.
6. Time measured from a positive-going input pulse from 0 to 0.4 V into the threshold to the drop from high to low of the output. Trigger is

One feature of the dual timer is that by utilizing both halves it is
possible to obtain sequential timing. By connecting the output of the
first half to the input of the second half via a 0.001µF coupling
