Control FETs on one wire, is it possible?

Suffered question control a small handful of field-effect transistors (15штук). After all, it is not advisable for each transistor to give a single Arduino pin. Based on this, caught the question: how to control this transistor with, say i2c or OneWire? Is it realistic?
Thanks for the answer)

If you need only the outputs (control transistor, relay, led) that is cheaper to use the shift register (the first nakupenda article: ). Management - SPI.
If you later need a full port, which can work as input or output, here's an article ( ) about the i2c expander ports.
For 1wire something similar happened, but immediately couldn't find.
