NOTES:
1. The junction temperature must be kept below 125°C for the D package and below 150°C for the N and F packages. At ambient temperatures
above 25°C, where this limit would be exceeded, the Maximum Allowable Power Dissipation must be derated by the following:
D package 115°C/W
N package 80°C/W
F package 100°C/W


Description

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 timers operate independently of each other, sharing only VCC and ground. The circuits may be triggered and reset on falling waveforms. The output structures may sink or source 200mA.
