TC7258 Overview:
TC7258 is an 8-channel hidden control driver IC designed specifically for LED screen line scanning screens. It integrates a line hidden circuit, a 74HC138 three eight decoder, and a power transistor internally.
When the power tube of TC7258 is turned off, the internal pull-down tube will open and absorb residual charges on the line with a constant current, which can eliminate dragging phenomenon and improve caterpillar phenomenon caused by LED leakage and short circuit.
TC7258‘s unique patented technology can completely eliminate ghosting, making it the chip with the best LED screen scanning display effect on the market.
TC7258 adopts the packaging form of SOP-16 and integrates an anti burn power transistor inside.
