TK15404
75 Ω VIDEO LINE DRIVER
FEATURES
■ Gain Set by External Components (6 dB typ.)
■ Internal 75 Ω Driver
■ Active High ON/OFF Control with Internal Pull-up
■ Very Low Standby Current (typ. I
STBY
≤ 25 µA)
■ Very Small SOT23-6 Package
■ Single +5 V Power Supply Operation
DESCRIPTION
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 V
is typically amplified 6 dB using external components to
produce a 2 V
signal into an AC-coupled 150 Ω load.
P-P
During standby (Pin 1 grounded), the TK15404 consumes
only 120 µW of power. Nominal power dissipation (no
input) is typically 32 mW.

MEASUREMENT METHOD
1. Supply Current (ICC)
The Pin 6 current is measured with no input signal and the Standby Pin (Pin 1) open.
2. Standby Supply Current (I
STBY
)
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) (V
THL
)
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) (V
TLH
)
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.
