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) Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14.4V Brightness Controlling Voltage, V3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14.4V Resolution Controlling Voltage, V4 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14.4V Contrast Controlling Voltage, V10 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14.4V Tint Controlling Voltage, V7 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14.4V Color Controlling Voltage, V9 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14.4V Auto Controlling Voltage, V8 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14.4V Luminance Input Signal Voltage, V5 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +5V Chrominance Signal Input Voltage, V13 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +2.5V Demodulator Input Signal Voltage, V25 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +5V R.G.B.
