NTE7167

NTE7167 Integrated Circuit Vertical Deflection Output Circuit Description: The NTE7167 is a vertical deflection output integrated circuit in a 7- Lead SIP type package designed for use in high- resolution television and CRT display systems that use a bus controller system signal processing IC. It can directly drive the deflection yoke (including the required DC component) from the bus controller system signal processing IC’s sawtooth waveform output. Since the NTE7167 has a maximum deflection current of 2.2AP - P, it is optimal for use in large aperture products, and is capable of driving 33 to 37 inch class monitors.
