Tl494 Circuit Diagram Fix -

Pin 13, the Output Control, acts as a logic toggle. The circuit diagram shows this pin connected to the internal flip-flop. When Pin 13 is tied to the 5V reference, the internal flip-flop is enabled, and the output transistors (Pins 8, 9, 10, 11) alternate in a push-pull configuration—ideal for driving a center-tapped transformer. When Pin 13 is grounded, the flip-flop is bypassed, and the output transistors switch in parallel. This allows the diagram to reveal the chip's versatility: it can drive a single output stage or a double-ended output stage depending solely on this wiring configuration.
