| TK15409 75 VIDEO LINE DRIVER FEATURES s Internal Y-C Summing Circuit s Voltage Gain is 6 dB Fixed s Internal 75 Driver s Active High ON/OFF Control s Very Low Standby Current (typ. ISTBY 25 A) s Very Small Output Capacitor Using SAG Function Pin s Very Small Package (SOT23L-8) s Single +5 V Power Supply Operation APPLICATIONS s s s s s s Video Equipment Digital Cameras CCD Cameras TV Monitors Video Tape Recorders LCD Projectors DESCRIPTION Operating from a single +5 V supply, the TK15409 is a video line driver IC that takes standard Y and C analog inputs and provides a composite analog output for driving 150 loads (75 resistor and 75 cable load). Internal summing of the Y and C inputs is performed to produce the composite video output. The luminance (Y) input is clamped at 1.25 V and amplified 6 dB; the chromanance (C) input is biased at 2.0 V and amplified 6 dB. The internal 1.5 k SAG function resistor provides gain compensation for low frequency signals. During standby (Pin 5 grounded), the TK15409 consumes only 127 W of power. Nominal power dissipation (no input) is typically 90 mW. The TK15409M is available in the very small SOT23L-8 surface mount package.
