Does anyone know where to get an integrated circuit
chip for a three button garage door controller made
by Lift-Master for Sears 139.53778. My copy has a Texas
Instruments #2335502T on it. I have tried to find
data sheets on the circuit but without luck.
The part number is probably propietary. But there
may be an equivilent on the market. My chip is
a miniature 16 pin surface mount type.
