8.3.1 Balanced High-Drive CMOS Push-Pull Outputs

A balanced output allows the device to sink and source similar currents. The high drive capability of this device creates fast edges into light loads, so routing and load conditions should be taken into consideration to prevent ringing. Additionally, the outputs of this device are capable of driving larger currents than the device can sustain without being damaged. The power output of the device must be limited to avoid thermal runaway and damage caused by over-current. Follow the electrical and thermal limits defined in the Absolute Maximum Ratings at all times.
