Filtering noise from a wire

[Demon]

The graph at the bottom of page 1 of the LTC4311 shows a total rise-time of about 1uS.

Would a LTC4311 be enough to process a rotary encoder with an MCP23017?

Would I be able to use I2CRead and I2CWrite with this device, or would I have to use another technique?


The 16F1946 is rated up to 400kHz according to Table 24-4, but there's this note under the table:

Note 1: The interface does not conform to the 400 kHz specification (which applies to rates greater than 100 kHz) in all details, but may be used with care where higher rates are required by the application.

(I'm using MCP23017 which are rated for 100kHz, 400kHz and 1.7 MHz)
