Maximum current on CD74HC4067
The 4067 is an analog multiplexer, not a power switch. It is not designed to supply any significant current to its outputs -- the datasheet specifies an "absolute maximum" of:


  DC Output Source or Sink Current per Output Pin: ±25 mA


This is because its intended application is for switching analog signals to high-impedance loads, like operational amplifiers or DACs.

A MOSFET or relay would be a more appropriate choice here.
