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 (1V_P-P typical) is internally
clamped at 1.25 V and amplified 6 dB to produce 2 V_P-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.
