WRITE CYCLE
A combination of Wn less than V
IL
(max) and En less than
V
IL
(max) defines a write cycle. The state of G is a “don’t care”
for a write cycle. The outputs are placed in the high-impedance
state when either G is greater than V
IH
(min), or when Wn is less
than V
IL
(max).
Write Cycle 1, the Write Enable-controlled Access is defined
by a write terminated by Wn going high, with En still active.
The write pulse width is defined by t
WLWH
when the write is
initiated by Wn, and by t
ETWH
when the write is initiated by En.
Unless the outputs have been previously placed in the high-
impedance state by G, the user must wait t
WLQZ
before applying
data to the nine bidirectional pins DQ(7:0) to avoid bus
contention.
Write Cycle 2, the Chip Enable-controlled Access is defined by
a write terminated by the latter of En going inactive. The write
pulse width is defined by t
WLEF
when the write is initiated by
Wn, and by t
ETEF
when the write is initiated by the En going
active. For the Wn initiated write, unless the outputs have been
previously placed in the high-impedance state by G, the user
must wait t
WLQZ
before applying data to the eight bidirectional
pins DQ(7:0) to avoid bus contention.
TYPICAL RADIATION HARDNESS
