NOTES: A. To minimize errors caused by noise at the chip select input, the internal circuitry waits for two rising edges and one falling edge
of the internal system clock after CS
↓
before responding to control input signals. The CS setup time is given by the tsu(CS)
specifications. Therefore, no attempt should be made to clock-in an address until the minimum chip select setup time has elapsed.
B. The output is 3-stated on CS going high or on the negative edge of the eighth I/O clock.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to digital ground with REF– and GND wired together (unless otherwise noted).
