567 IC Pulse Generator With 25% Active Factor

Unique applications of 567 tone/frequency decoder IC? Here is one of them: pulse generator with 25% duty cycle (active factor). This signal generator produce square wave pulse, and you use it as clock source or other purpose. Here is the schematic diagram of the circuit.

The frequency of this pulse generator is formulated as f=1/(1.1xR1xC1). [Circuit’s schematic diagram source: Philips Semiconductors Datasheet]
