The lowest input impedance can be derived from the worst-case input leakage current: 5 V / 5 µA = 1 MΩ. The typical leakage current is many orders of magnitude smaller, and is approximately zero at room temperature, so the upper limit of the input impedance is approximately infinite.
Hey Joe,
It can be anywhere from 10 to 25 ohms depending on the supply voltage.
Edit: Sorry I misread input for output, refer to Clemens' response on the input impedance.
