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 becomes 3-state on CS going high or on the negative edge of the eighth I/O clock. absolute maximum ratings over operating free-air temperature range (unless otherwise noted)† Supply voltage, VCC (see Note 1) 6.5 V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

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.
