FIGURE 1. READ CYCLE
The address information is latched in the on-chip registers
on the falling edge of E (T = 0), minimum address setup and
hold time requirements must be met. After the required hold
time, the addresses may change state without affecting
device operation. During time (T = 1), the outputs become
enabled but data is not valid until time (T = 2), W must
remain high throughout the read cycle. After the data has
been read, E may return high (T = 3). This will force the out-
put buffers into a high impedance mode at time (T = 4). G is
used to disable the output buffers when in a logical “1” state
(T = -1, 0, 3, 4, 5). After (T = 4) time, the memory is ready for
