Note: 1. Pulse Generator: Rate ≤ 1.0 MHz, tF ≤ 2.5 ns,
tR ≤ 2.5 ns.
2. AC tests are done with a single bit switching, and
timings need to be derated when multiple outputs
are switching in the same direction simultaneously.
This derating should not exceed 0.5 ns for 16 inputs
switching simultaneously.
