- Single Ended Output Slew Rate
With the reference load for timing measurements, output slew rate for falling and rising edges is defined
and measured between VOL(AC) and VOH(AC) for single ended signals as shown in Table.

Single-ended output slew rate for rising edge VOL(AC) VOH(AC) [VOH(AC) - VOL(AC)] / DeltaTRse
Single-ended output slew rate for falling edge VOH(AC) VOL(AC) [VOH(AC) - VOL(AC)] / DeltaTFse
NOTE: Output slew rate is verified by design and characterization, and may not be subject to production test.
