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 TK15404 Operating from a single +5 V supply, the TK15404 is a single-channel video driver IC that takes a standard video signal as the analog input and provides a buffered analog output for driving a 150 Ω load (series 75 Ω resistor and 75 Ω cable load). The standard video input signal (1 VP-P) is typically amplified 6 dB using external components to produce a 2 VP-P signal into an AC-coupled 150 Ω load. During standby (Pin 1 grounded), the TK15404 consumes only 120 µW of power. Nominal power dissipation (no input) is typically 32 mW. The TK15404M is available in the very small SOT23-6 surface mount package. 01 S STANDBY VCC OUTPUT GND -INPUT +INPUT BLOCK DIAGRAM VCC 75 Ω DRIVER ORDERING INFORMATION TK15404M STANDBY GND Tape/Reel Code TAPE/REEL CODE TL: Tape Left January 2000 TOKO, Inc.

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. 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. 7. 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. Furthermore, 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 10 MHz. January 2000 TOKO, Inc. Page 3 TK15404 MEASUREMENT METHOD 8. Total Harmonic Distortion (THD) The TP3 signal is measured when a 1 kHz 1 VP-P input signal is applied to TP1. 9. 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%. 10. Signal to Noise Ratio (S/N) The signal to noise ratio is measured at TP3 when a pedestal input signal is applied to TP1. 11. Differential Gain (DG) SW1 is closed to change the input bias voltage. The differential gain is measured at TP3 when a staircase waveform of 10 steps is applied to TP1. 12. Differential Phase (DP) SW1 is closed to change the input bias voltage. The differential phase is measured at TP3 when a staircase waveform of 10 steps is applied to TP1. TYPICAL PERFORMANCE CHARACTERISTICS SUPPLY CURRENT VS. SUPPLY VOLTAGE SUPPLY CURRENT VS.
