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
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.

NOTES:
1. Supply current when output is high is typically 1.0mA less.
2. Tested at VCC=5V and VCC=15V.
3. This will determine maximum value of RA+RB. For 15V operation, the max total R=10MΩ, and for 5V operation, the maximum total
R=3.4MΩ.
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 0.4V. To disable reset
function, the voltage at reset pin has to be greater than 1V.
6. Time measured from a positive-going input pulse from 0 to 0.4 VCC into the threshold to the drop from high to low of the output. Trigger is
tied to threshold.
The first half of the timer is started by momentarily connecting Pin 6
to ground. When it is timed out (determined by 1.1R1C1) the second
half begins. Its duration is determined by 1.1R2C2.
TYPICAL APPLICATIONS
One feature of the dual timer is that by utilizing both halves it is
possible to obtain sequential timing. By connecting the output of the
first half to the input of the second half via a 0.001µF coupling
capacitor sequential timing may be obtained. Delay t1 is determined
by the first half and t2 by the second half delay.
