PDF datasheet for the TDA4867J, a Philips-family vertical deflection output IC found in CRT monitors and TV sets. The document lists the pin functions, absolute maximum ratings, electrical characteristics and a reference application circuit. A technician uses it to check supply and flyback voltages on the chip, verify external parts in the deflection stage and confirm a suitable substitute. Faults like a single horizontal line on screen often point to this stage, so measure around the IC before swapping it.
