Once downloaded, you need to place the library files in the correct directories so LTspice can find them. The process is straightforward: Pin 13 dictates whether the dual output transistors

: Pull Pin 9 and Pin 10 up to your power rail using The process is straightforward: : Pull Pin 9

: Use a P-Channel MOSFET or a NPN transistor driven by the TL494's uncommitted collectors (Pins 8 and 11).
