Functions
A18 to A0
Address input
Supply the memory address to these pins.
The address is latched internally during a write cycle.
These pins output data during a read cycle and input data during a write cycle.
Data is latched internally during a write cycle.
Outputs go to the high-impedance state when either OE or CE is high.
DQ7 to DQ0
Data input and output
CE
Chip enable
The device is active when CE is low.
When CE is high, the device becomes unselected and goes to the standby state.
OE
Output enable
Makes the data output buffers active.
OE is a low-active input.
WE
Write enable
Makes the write operation active.
WE is a low-active input.

N.C.
Power supply
Apply 5 V (±10%) to this pin.
Ground
No connection
These pins must be left open.
