Description

The NTE843 is a linear IC synchronous detector employing a phaselocked oscillator to demodulate the 45.75MHz video IF signals in colorTV receivers.  The NTE843 features AFT voltage for DC con-trol of the tuner; an adjustment for the zerocarrier DC level at the video output terminal; an amplifier  arrangement for inverting noise impulses toward the black level; and a separate output terminal (noninverting) for the sound IF.

The NTE843 is supplied in a 16lead plastic "powerslab" dualinline package.

The "powerslab" package of NTE843 has an inherently low junctiontocase (slab) thermal resistance and lends itself to a wide variety of heatsink methods, depending on the application requirements.
