AC CharacteristicsD80L186EC16
(Continued)
NOTES:
1. See
AC Timing Waveforms
, for waveforms and definition.
2. Measure at V
IH
for high time, V
IL
for low time.
3. Only required to guarantee I
CC
. Maximum limits are bounded by T
C
, T
CH
and T
CL
.
4. Specified for a 50 pF load, see Figure 14 for capacitive derating information.
5. Specified for a 50 pF load, see Figure 15 for rise and fall times outside 50 pF.
6. See Figure 15 for rise and fall times.
7. T
CHOV1
applies to BHE (RFSH), LOCK and A19:16 only after a HOLD release.
8. T
CHOV2
applies to RD and WR only after a HOLD release.
9. Setup and Hold are required to guarantee recognition.
10. Setup and Hold are required for proper operation.
