Operating Rules
1. An external resistor (R
X
) and external capacitor (C
X
) are
required as shown in the Logic Diagram.
TL/F/6611–3
2. The value of C
X
may vary from 0 to any necessary value
available. If, however, the capacitor has leakages ap-
proaching 3.0
m
A or if stray capacitance from either ter-
minal to ground is more than 50 pF, the timing equations
may not represent the pulse width obtained.
3. The output pulse with (t) is defined as follows:

4. If electrolytic type capacitors are to be used, the following
three configurations are recommended:
A. Use with low leakage capacitors:
The normal RC configuration can be used predictably
only if the forward capacitor leakage at 5.0V is less
than 3
m
A, and the inverse capacitor leakage at 1.0V is
less than 5
m
A over the operational temperature
range.
