NOTES:

1. Industrial temperature range product for 20ns speed grade is available as a standard device. All other speed grades are available by special order.

2. Only applies for a clock edge that does a FIFO read.

3. Requirement to count the clock edge as one of at least four needed to reset a FIFO.

4. Skew time is not a timing constraint for proper device operation and is only included to illustrate the timing relationship between CLKA cycle and CLKB cycle.
