Vertical Deflection Output Circuit for Color TV
Description:
The NTE7056 is an integrated circuit in a 9−Lead SIP type package designed for use as a vertical
deflection output circuit for 9” to 21” color television sets. This device requires no voltage−boosted
pulses and can therefore be connected to a chrominance−video deflection IC such as the NTE1793,
deflection ICs such as the NTE1664, or similar devices. The package is designed for one−point fixing,
reducing installation man−hours.
Features:
D Requires High Power Voltage Only During Flyback Time, Greatly Reducing Power Consumption.
D Deflection Control in the Preceding Stage can be used both by Discrete Components and ICs.
