PCF8574 Inputs

Has anyone used the PCF8574 as an input expander?
I've tried this library, https://github.com/BetaRavener/micropyt ... er/PCF8574 and have been successful using it to turn on LEDs etc, but can't seem to get inputs working. pcf.read8() returns a [0] regardless of input status.
Thanks.
