TC7258
TC7258 is an 8-channel blanking control driver IC designed for LED screen line scanning screen, which integrates a line blanking circuit, 74HC138 38 decoder and power tube.
When the TC7258 power tube is closed, the internal pulldown tube will open and absorb the residual charge in the line with a constant current, which can eliminate the phenomenon of dragging, and also improve the caterpillar phenomenon caused by LED leakage and short circuit.
When the TC7258 power tube is closed, the internal pulldown tube will open and absorb the residual charge in the line with a constant current, which can eliminate the phenomenon of dragging, and also improve the caterpillar phenomenon caused by LED leakage and short circuit.
TC7258 Description:
TC7258 is an 8-channel blanking control driver IC designed for LED screen line scanning screen, which integrates a line blanking circuit, 74HC138 38 decoder and power tube.
When the TC7258 power tube is closed, the internal pulldown tube will open and absorb the residual charge in the line with a constant current, which can eliminate the phenomenon of dragging, and also improve the caterpillar phenomenon caused by LED leakage and short circuit.
The unique patented technology of TC7258 can completely eliminate ghost phenomenon, and it is the best chip for line scanning display of LED screen on the market.
