I don't know you requirements other than expand ports via i2c, so this may
not be exactly what you need, but Microchip makes a few of those.  Both
the MCP23016/17 are 16 bit i/o port expanders, the 16 vcc is 2.0 to 5.5
and the 17 vcc is 1.8 to 5.5, also, the 16 has a max bus frequency of
400kbits/sec while the 17 is 1700 kbits/sec.  The budgetary price is $1.15
for the 16 and $0.86 for the 17.

Good luck.
