somebody gave me some boards from a toy car, the emitter and the receiver
the emitter contains an ic :TA7333 and has 9 pins inline.
the receiver contains TA7657, 14 pins, dual in line.
i think that they are either tone modulators/demodulators, or they are some serial to paralel/paralel to serial convertors.
so i need some datasheets or at least the pins and some circuits with those will be great.'
i cand use the whole boards because most of the other components are missing.
