because the steering flip-flop divides the frequency by two: tl494 ltspice
Locate a .subckt file for the TL494. If you have the raw text code, follow these steps: Open a text editor (like Notepad). Paste the TL494 SPICE text code.
Texas Instruments provides a PSpice model for the TL494. While PSpice models often work in LTspice, they require conversion. Download the .lib or .cir file from TI’s website, then use the .include directive in LTspice. Connect to provide the internal stable 5V reference
