... Output Connection (with pin 15). The output stage is a "H" bridge formed by four transistors and four diodes suitable for switching applications. A parallel RC network connected to this pin sets the OFF time of the lower power transistors. The pulse generator is a monostable triggered by the rising edge of ...
