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.
