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.
Features:
D Low Power Dissipation due to the Provision of a Built - In Pump Circuit
D Vertical Output Circuit
D On - Chip Thermal Protection Circuit
D Good Crossover Characteristics
D Supports DC Coupling
