The Mk484 IC has automatic gain and up to 72 db gain. It is cased in a TO-92 Case looks like a transistor. The MK 484 runs on 1.1 to 1.8 volts so a single 1-1/2 volt battery will work.

The MK484 MK-484 MK 484 is a AM radio receiver replaces the older ZN414. The only difference between the MK484 and the ZN414 is pin out.

The YS414, TA7642, UTC7642, CD7642 are all the same devices as the MK484 only they are made by different manufactures.

I do not sell equivalent parts if your order a MK484 I ship a MK484 not one of the others.
