NTE1846
Integrated Circuit
NTSC System Single鈥揅hip Color TV Signal Processor
Description:
The NTE1846 is an integrated circuit in a 52鈥揕ead DIP type package designed for use as a color TV
signal processor. This device contains signal processing functions for video IF, sound IF, video, color,
deflection signals, on a single chip.
Combined with a tuner and a simple output stage of discreet transistors, the NTE1846 enables more
rationalized designs for color TV sets.
Features:
D
Large Integration Enables Rationalization and High Reliability of Equipment and Low Power
Consumption.
D
A Direct Output Pin for Sound FM Detector is Provided, Applicable to Sound Multiplexing.
D
