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.

FEATURES

•Turn-off time less than 2µs (556-1)

•Maximum operating frequency >500kHz (556-1)

•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

•SE556-1 compliant to MIL-STD or JAN

APPLICATIONS

•Precision timing

•Sequential timing

•Pulse shaping

NOTES:

1. Supply current when output is high is typically 1.0mA less.

2. Tested at V

CC

=5V and VCC=15V.

3. This will determine maximum value of R

A+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 V

CC

into the threshold to the drop from high to low of the output. Trigger is

tied to threshold.

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 t

1

is determined

by the first half and t

2

by the second half delay.

The first half of the timer is started by momentarily connecting Pin 6
to ground. When it is timed out (determined by 1.1R

1C1

) the second

half begins. Its duration is determined by 1.1R

2C2

.
