DEVICE OPERATION
Read
Data stored in the CAT28LV64 is transferred to the data
bus when WE is held high, and both OE and CE are held low.
The data bus is set to a high impedance state when either CE
or OE goes high. This 2 ? line control architecture can be used
to eliminate bus contention in a system environment.

Byte Write
A write cycle is executed when both CE and WE are l ow,
and OE is high. Write cycles can be initiated using either WE
or CE, with the address input being latched on the falling
edge of WE or CE, whichever occurs last. Data, conversely,
is latched on the rising edge of WE or CE, whichever occurs
first. Once initiated, a byte write cycle automatically erases
the addressed byte and the new data is written within 5 ms.
