| NTE1556 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: (TA = +25C unless otherwise specified) Maximum Supply Voltage, VCCmax . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Pin Current Pin10, I10 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20mA Pin6, I6 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -10mA Pin14, I14 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -10mA Allowable Power Dissipation (TA +65C), Pdmax . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to +75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +125C Electrical Characteristics: (TA = +25C, VCC = 12V unless otherwise specified) Parameter Circuit Current LED Driver Output High Level Low Level Tint Control Output High Level Low Level Color Control Output High Level Low Level Symbol I15 V10H V10L V6H V6L V14H V14L Test Conditions SG2 = 65mVPP, SG3 = 0, SG5 = 0.55VPP SW1: OFF SW1: ON SW1: ON, V4 = 0V SW1: ON, V4 = 2V SW1: ON, V13 = 0V SW1: ON, V13 = 1.7V Min - 10.9 - - - - - Typ 15.5 - - 10.0 5.65 8.7 3.3 Max - - 0.4 - - - - Unit V V V V V V V Electrical Characteristics (Cont'd): (TA = +25C, VCC = 12V unless otherwise specified) Parameter VIR Tint Adjustment Voltage Tint Control Characteristics High Level Low Level Color Control Characteristics High Level Low Level VIR Killer Input Level Symbol V6 V4H V4L V13H V13L VKIL SW1: ON SG2 = 0 SG2 = 65mVPP SG5 = 650mVPP SG5 = 550mVPP SG3 level at which LED is turned OFF Pin Connection Diagram Test Conditions Min - 6 - 6 - - Typ 1.6 - - - - 0.28 Max - - 50 - 50 - Unit VPP VPP mVPP VPP mVPP VPP VCC 2 1 Flyback Pulse Input 2 R-Y Input 3 Auto Tint Input 4 Tint Fine Adjust Output 5 Tint Control Voltage Output 6 Composite Video 7 GND 8 16 Composite Sync 15 VCC 1 14 Color Control Output 13 Manual Color 12 B-Y Input 11 Y Input 10 VIR Indicator 9 RC Filter 16 9 .260 (6.6) Max 1 8 .785 (19.9) Max .200 (5.08) Max .245 (6.22) Min .100 (2.54) .700 (17.7) .300 (7.62) |
