Hi brothers, first of all, have a greeting, to have, I have an Organ (electric piano) Yamaha model HS5, which wiped the part of the pedals damaging an integrated, the TC4050BP, the thing is that I can not say said integrated ... yes Can someone tell me what the replacement is? Thanks in advance...

That integrated is a sextuple not cmos and is most common, You can replace it with the CD4049. http://www.ti.com/lit/ds/schs046j/schs046j.pdf
