NTE7056 Integrated Circuit 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.
