NTE NTE1416

NTE1416
Integrated Circuit
Chrominance and Luminance Processor for
NTSC Color TV
Description:
The NTE1416 is an MSI integrated circuit in a 28–Lead DIP type package designed for NTSC systems
to process both color and luminance signals for color televisions. This device provides two functions:
The processing of color signals for the band pass amplifier, color synchronizer, and demodulator circuits and also the processing of luminance signal for the luminance amplifier and pedestal clamp circuits. The number of peripheral parts and controls can be minimized and the manhours required for
assembly can be considerbly reduced.
Features:
D Few External Components Required
D DC Controlled Circuits make a Remote Controlled System Easy
D Protection Diodes in every Input and Output Pin
D “Color Killer” Needs No Adjustements
D “Contrast” Control Does Not Prevent the Natural Color of the Picture, as the Color Saturation
Level Changes Simultaneously
D ACC (Automatic Color Controller) Circuit Operates Very Smoothly with the Peak Level Detector
D “Brightness Control” Pin can also be used for ABL (Automatic Beam Limitter)
