PIN DESCRITPION
Addresses (A0-A12). The address inputs select
an 8-bit memory location during a read or write
operation.
Warning: DU = Don’t Use.
Chip Enable (E). The chip enable input must be
low to enable all read/write operations. When Chip
Enable is high, power consumption is reduced.
Output Enable (G). The Output Enable input con-
trols the data output buffers and is used to initiate
read operations.
