It looks to me like 3 IR links are needed:

1. One TO the 24C16 for the clock.

2,  One TO the 24C16 for Data OUT.

3. One FROM the 24C16 for Data IN

If the links are modulated (38K/40K) the clock
speed of the 24C16 will need to be 1/5
the modulation speed or slower.

At the 24C16, the DATA IN and DATA OUT are
OR'd at the SDA pin.

BTW: an SPI chip will be more reliable in this
mode.
