TK15406 75 Ω VIDEO LINE DRIVER APPLICATIONS FEATURES ■ ■ ■ ■ ■ Internal 75 Ω Driver Active High ON/OFF Control with Internal Pull-up Very Low Standby Current (typ. ISTBY ≤ 25 µA) Very Small SOT23-6 Package Single +5 V Power Supply Operation ■ ■ ■ ■ ■ ■ Video Equipment Digital Cameras CCD Cameras TV Monitors Video Tape Recorders LCD Projectors DESCRIPTION TK15406 Operating from a single +5 V supply, the TK15406 is a single-channel video line driver IC that takes a standard video analog input and provides a buffered analog output for driving a 150 Ω load. The standard video input signal (1 VP-P typical) is internally biased at 2.5 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 1 grounded), the TK15406 consumes only 120 µW of power. Nominal power dissipation (no input) is typically 32 mW. 01 S STANDBY VCC OUTPUT GND N/C The TK15406M is available in the very small SOT23-6 surface mount package.

Supply Current (ICC) The Pin 6 current is measured with no input signal and the Standby Pin (Pin 1) open. 2. Standby Supply Current (ISTBY) The Pin 6 current is measured when the Standby Pin (Pin 1) is connected to ground. 3. Standby Terminal Current (IOS) The Pin 1 current is measured when Pin 1 is connected to ground. 4. Threshold Voltage (High to Low) (VTHL) The Pin 1 voltage is measured at the point which changes the device from operating mode into standby mode. 5. Threshold Voltage (Low to High) (VTLH) The Pin 1 voltage is measured at the point which changes the device from standby mode into operating mode. 6. Bias Voltage (VBIAS) The DC voltage at Pin 4 is measured with no input signal. 7. Voltage Gain (GVA) The voltage gain equation is as follows: GVA = 20 log10 V2/V1 Where V1 is the input voltage at TP1 and V2 is the measured output voltage at TP2. 8. Frequency Response (fr) The frequency response equation is as follows: fr = 20 log10 V2/V1 Where V1 is the measured TP3 voltage when the TP1 input frequency is set to 1 MHz and V2 is the measured TP3 voltage when the TP1 input frequency is set to 5 MHz. 9. Total Harmonic Distortion (THD) The TP3 signal is measured when a 1 kHz 1 VP-P input signal is applied to TP1. 10. Maximum Output Voltage (VOUT(MAX)) A 1 kHz input signal is applied to TP1 and the amplitude is slowly increased. The output voltage at TP2 is measured at the point the THD reaches 10%.
