General
5.1 AC electrical characteristics
Unless otherwise specified, propagation delays are measured from the 50% to the 50%
point, and rise and fall times are measured at the 20% and 80% points, as shown in the
following figure.
Figure 1. Input signal measurement reference
All digital I/O switching characteristics, unless otherwise specified, assumes:
1. output pins
• have CL=30pF loads,
• are slew rate disabled, and
• are normal drive strength
