Data Input/output To output data during Read cycles and receive input data during Write cycles.
Data is internally latched during a Write cycle.
The outputs are in tri-state when OE# or CE# is high.
CE# Chip Enable To activate the device when CE# is low.
OE# Output Enable To gate the data output buffers.
WE# Write Enable To control the Write operations.
