Overview
TK15412 75 Ω VIDEO LINE DRIVER FEATURES s Fixed Gain (6 dB) s Internal 75 Ω Driver with Clamp Circuit s Very Small Output Capacitor Using SAG Function Pin s Active High ON/OFF Control s Very Low Standby Current (typ.
ISTBY ≤ 25 µA) s 2 Input/1 Output Video Switch 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 TK15412 is a single-channel video line driver IC that takes two standard video analog inputs and provides one buffered analog output for driving a 150 Ω load.
The TK15412 features a built-in 2 input/1 output video switch on the input.
The selected video input signal (1VP-P typical) is internally clamped at 1.
25 V and amplified 6 dB to produce 2 VP-P (typical) into a series 75 Ω resistor and 75 Ω cable load.
During standby (Pin 5 grounded), the TK15412 consumes only 125 µW of power.
Nominal power dissipation (no input) is typically 73 mW.
The TK15412M is available in the SOT23L-8 surface mount package.
