| NJM2249 3 INPUT VIDEO SWITCH • GENERAL DESCRIPTION The NJM2249 is 3-input video switch for video and audio signal. One input terminals has sink-chip clamp function and so it is applied to fixed DC level of video signal. Two other input terminals are transistor base input for luminant signal and so luminant level may be easily fixed by outer circuit. Its operating supply voltage range is to 13V and bandwidth is 10MHz. Cross-talk is 70dB at 4.43MHz . • FEATURES ● Operating Voltage V+ = +4.75V to +13V ● 3 Input - 1 Output ● Internal Clamp Function VIN1 ● Internal Luminance Signal Control Function VIN2, VIN3 ● Cross - talk 70dB at 4.43MHz ● Wide Frequency Range ● Package Outline DIP8, DMP8, SIP8, SSOP8 ● Bipolar Technology • APPLICATION ● VCR, Video Camera, AV-TV, Video Disc Player • PIN CONFIGURATION • PACKAGE OUTLINE NJM2249D NJM2249M NJM2249V NJM2249L NJM2249D NJM2249M NJM2249V • BLOCK DIAGRAM NJM2249L • INPUT CONTROL SIGNAL-OUTPUT SIGNAL SW1 L H SW2 L H OUTPUT SIGNAL VIN1 VIN2 VIN3 Ver.2004-02-17 NJM2249 • ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage SYMBOL V+ Power Dissipation Operating Temperature Range Topr Storage Temperature Range Tstg RATINGS 15 DIP8 500 DMP8 300 SSOP8 250 SIP8 800 -20 to +75 -40 to +125 Ta = 25°C UNIT V mW °C °C • ELECTRICAL CHARACTERISTICS V+ = 5V, Ta = 25°C PARAMETERS SYMBOLS TEST CONDITIONS MIN.
