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 A outputs, or any two B outputs, with equal loading.
3. Between any clock A output and any clock B output with INA connected to INB, and equal loading.
4. See discussion and graph of speed versus load.
