DESCRIPTION
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
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 200 mA.
FEATURES
Timing from microseconds to hours
Replaces two 555 timers
Operates in both astable and monostable modes
High output current
Adjustable duty cycle
TTL compatible
Temperature stability of 0.005%/°C
