    "short killer pro" Component identification help

    Hello friends,

    I have a device called "short killer pro". It becomed damaged. Now, after changing 4 ICs it is working again, BUT I don't have neither voltage and intensity reading in the front display (the adjustments are working fine both for V and A, but there is no indication, as I said before). I did not find out any firmware update for the Altera microcontroller it uses (the rest of the functions are working, but the buzzer, for example). And I am suspecting about this IC, but I am not able to decipher which one it is. I see it is from Texas Instruments, but nothing more. It is a SOIC-10 package. Please, if somebody of you can help me to know which one it is, it will be great. I will include a pic with the IC. Thanks in advance for your help, as ever!.
