(Plastic Package)

ORDER CODE : TDA1675A

DESCRIPTION

The TDA1675A is a monolithic integrated circuit in

15-lead Multiwatt

and very efficient vertical deflection circuit intended

for direct drive of the yoke of 110

tubes. It offers a wide range of applications also in

portable CTVs, B&W TVs, monitors and displays.
