Notes:1 Alloutput specifications are measured from the 1.4 V of the rising edge of SYSCLK to the TTL level (0.8 V or 2.0 V) of the signal in question. Both
input and output timings are measured at the pin. See Figure 7.
2. All maximum timing specifications assume CL = 50 pF.
3. This minimum parameter assumes CL = 0 pF.
4. SYSCLK to output valid (5.5 V to 0.8 V) includes the extra delay associated with discharging the external voltage from 5.5 V to 0.8 V instead of
from Vdd to 0.8 V (5 V CMOS levels instead of 3.3 V CMOS levels).
5. tsysclk is the period of the external bus clock (SYSCLK) in nanoseconds (ns). The numbers given in the table must bemultipliedbytheperiodof
SYSCLK to compute the actual time duration (in nanoseconds) of the parameter in question.
6. Output signal transitions from GND to 2.0 V or Vdd to 0.8 V.
7. Nominal precharge width for ABB and DBB is 0.5 * tsysclk.
8. Nominal precharge width for ARTRY is 1.0 * tsysclk.
