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. CLK1 in the MK2049-02 may have the rising or falling edge aligned with the rising edge of CLK2. See the INPUT AND

OUTPUT SYNCHRONIZATION section for more details.
