Does anyone recognize the IC below that I have identified some of the pins? It's on a model ZW20-J radio receiver. When you push a button on the remote control, the corresponding data pin on this chip goes high. Or at least it used to, until I accidentally shorted it with +12v using my fat multi meter probe (topic covered in another thread). The PCB maker filed off the markings on the chips. I showed the other side of the PCB as well just in case it helps.
