hi im working on a project that needed to interface mmc with eeprom, to transfer data from mmc to eeprom, im using atmega328 and 24c32 eeprom, problem i m facing is my circuit works with one cd4050 E4 ic, but when i replace ic with any other cd4050 ic it doesnot work.
i connected cd4050 with differen serial no, also used hd14050, but it does not work.
so i cannot make copy of my circuit.
what could be the problem???
