Notes
14. Test conditions for all parameters other than tri-state parameters assume signal transition time of 1 V/ns, timing reference levels of V , input pulse levels of 0 to
TH
V
, and output loading of the specified I /I as shown in Table 1 on page 5.

write and any of these signals can terminate a write by going INACTIVE. The data input setup and hold timing should be referenced to the edge of the signal that
terminates the write.
