Dual timer

NE/SA/SE556/NE556-1

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
