Electrical Specifications

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. Within any bank of four outputs, with equal loading.

3. Between any two banks of four with their inputs connected together, and equal loading.

4. At VDD = 3.3 V, 70°C, series termination of 33

Ω per pin, 8 pF load per pin.

5. See discussion and graph of speed versus load.
