Operating Rules
(Continued)
8. Output pulse width variation versus V
CC
and tempera-
tures: Figure 6 depicts the relationship between pulse
width variation versus V
CC
, and Figure 7 depicts pulse
width variation versus temperatures.
FIGURE 6.
FIGURE 7.
9. Under any operating condition C
X
and R
X
must be kept
as close to the one-shot device pins as possible to min-
imize stray capacitance, to reduce noise pick-up, and
to reduce I-R and Ldi/dt voltage developed along their
connecting paths. If the lead length from C
X
to pins (6)
and (7) or pins (14) and (15) is greater than 3 cm, for
example, the output pulse width might be quite different
from values predicted from the appropriate equations.
A non-inductive and low capacitive path is necessary to
ensure complete discharge of C
X
in each cycle of its
operation so that the output pulse width will be accu-
rate.
10. The C
EXT
pins of this device are internally connected to
the internal ground. For optimum system performance
they should be hard wired to the system
’
s return
ground plane.
11. V
CC
and ground wiring should conform to good high-
frequency standards and practices so that switching
transients on the V
CC
and ground return leads do not
cause interaction between one-shots. A 0.01
μ
F to 0.10
μ
F bypass capacitor (disk ceramic or monolithic type)
from V
CC
to ground is necessary on each device. Fur-
thermore, the bypass capacitor should be located as
close to the V
CC
-pin as space permits.
Note: For further detailed device characteristics and output per-
formance please refer to the Fairchild Semiconductor one-shot
application note AN-372.
