Integrated Circuit
VIR Signal Processor for Color TV
Description:
The NTE1556 is a monolithic digital integrated circuit in a 16–Lead DIP type package which automatically
corrects the tint (hue) and color (chroma) of color TVs using VIR signals. This device constantly provides
optimum colors when added to the chroma circuit.
Features:
D Single Chip Construction with Functional Circuits for VIR Signal Detection, Tint Control, and
Color Control
D Low Power Consumption
D Few External Components Required and can be used without any Adjustments
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
