PRELIMINARY INFORMATION
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. Typical values are at 25°C.
3. See the selection table on page two for allowable input clock ranges. For a high input clock, VDD can only be 5V.
