Note:
1. Pulse Generator: Rate
≤
1.0 MHz, t
F
≤
2.5 ns,
t
R
≤
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.
