Integrated Circuit
Vertical Deflection Output Circuit
for Color TV
Description:
The NTE1767 is a vertical deflection output circuit in a 8–Lead SIP type package for use in Color TV
applications of 22 inch or larger. This device requires no voltage–boosted pulses and, therefore, can
be connected to a chrominance–video deflection circuit (NTE1793), deflection circuit (NTE1664), or
the like.
Features:
D Requires High Power Voltage only during Flyback Time, Greatly Reducing Power Consumption
D Deflection Control in the Preceeding Stage can be used both by Discrete Components and ICs
