NOTES
1. All voltages referenced to VSS (GND).
2. ICC limit shown is for absolute worst case switching of
ADDR, ADDR\, ADDR, etc.
3. ICC is dependent on output loading and cycle rates.
4. This parameter is guaranteed but not tested.
5. Test conditions as specified with the output loading
as shown in Fig. 1 unless otherwise noted.
6. tLZCE, tLZWE, tLZOE, t HZCE, tHZOE and tHZWE
are specified with CL = 5pF as in Fig. 2. Transition is
measured ±200mV from steady state voltage.
7. At any given temperature and voltage condition,
tHZCE is less than tLZCE, and tHZWE is less than
tLZWE.
8. WE\ is HIGH for READ cycle.
9. Device is continuously selected. Chip enables and
output enables are held in their active state.
10. Address valid prior to, or coincident with, latest
occurring chip enable.
11. tRC = Read Cycle Time.
12. Chip enable and write enable can initiate and
terminate a WRITE cycle.
13. Output enable (OE\) is inactive (HIGH).
14. Output enable (OE\) is active (LOW).
15. ASI does not warrant functionality nor reliability of
any product in which the junction temperature
exceeds 150°C. Care should be taken to limit power to
acceptable levels.
