Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged exposure
to levels above the operating limits but below the Absolute Maximums may affect device reliability.
2. Between any two outputs, with equal loading.
3. At VDD = 3.3 V, 70°C, series termination of 33 Ω per pin , 8 pF load per pin.
4. See discussion and graph of speed versus load, Graph 1 on following page.
