Operating Rules

TLF6611 – 3

1 An external resistor (RX) and external capacitor (CX) are

required as shown in the Logic Diagram

2 The value of CX may vary from 0 to any necessary value

available If however the capacitor has leakages ap-

proaching 30 mA 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 50V is less

than 3 mA and the inverse capacitor leakage at 10V is

less than 5 mA over the operational temperature
