Single Ended Output Slew Rate
When the Reference load for timing measurements, output slew rate for falling and rising edges is defined
and measured between V
and measured between V
OL(AC)
and V
OH(AC)
for single ended signals are shown in table and Figure below.
Notes:
1. Output slew rate is verified by design and characterisation, and may not be subject to production test.
