I'm looking for an I2C Port Expander for both 8 and 16-bits,
preferably with light pull-ups when configured as inputs.

I have found two possible devices:
  Philips  PCA9555  (16-bits with pull-ups)
  Microchip MCP23016 (16-bits w/o pull-ups)
            MCP23008 (8-bits w/o pull-ups)

I was able to get some samples of the Microchip part but I'm having a
problem with the Philips.  Anyone have experience with using a port
expander and if so, what device was chosen?

Thanks,
