DESCRIPTION
PIN CONFIGURATION
Both the NE556 and SA556 Dual Monolithic timing circuits are highly
stable controllers capable of producing accurate time delays or
oscillation. The 556 is a dual 555. Timing is provided by an external
resistor and capacitor for each timing function. The two timers

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 0.4 V. To disable reset
function, the voltage at reset pin has to be greater than 1 V.
