NE/SA/SE556/NE556-1
Dual timer
353
August 31, 1994
853-0035 13721
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 V
CC
and
ground. The circuits may be triggered and reset on falling
waveforms. The output structures may sink or source 200mA.
