WRITE Mode
The M48T08/18/08Y is in the WRITE Mode when-
ever W, E1, and E2 are active. The start of a
WRITE is referenced from the latter occurring fall-
ing edge of W or E1, or the rising edge of E2. A
WRITE is terminated by the earlier rising edge of
W or E1, or the falling edge of E2. The addresses
must be held valid throughout the cycle. E1 or W
must return high or E2 low for a minimum of t
E1HAX
or t
E2LAX
from Chip Enable or t
WHAX
from WRITE
Enable prior to the initiation of another READ or
WRITE Cycle. Data-in must be valid t
DVWH
prior to
the end of WRITE and remain valid for t
WHDX
af-
terward. G should be kept high during WRITE Cy-
cles to avoid bus contention; however, if the output
bus has been activated by a low on E1 and G and
a high on E2, a low on W will disable the outputs
t

after W falls.
