1. Maximum power and current consumption over the full operating temperature and power supply voltage range. Includes all
channels.
2. Power consumption includes power absorbed by line load and external transmitter components.
3. T1 maximum values measured with maximum cable length (LEN = 111). Typical values measured with typical cable length
(LEN = 101).
4. Digital inputs are within 10% of the supply rails and digital outputs are driving a 50pF load.
