The conversion cycle, which requires 44 system clock periods, initiates on the tenth falling edge of the I/O clock after CS goes low for the channel whose address exists in memory at that time. When CS is kept low during conversion, the I/O clock must remain low for at least 44 system clock cycles to allow the conversion to complete. B. The most significant bit (MSB) is automatically placed on the DATA OUT bus after CS is brought low. The remaining nine bits (A8–A0) clock out on the first nine I/O clock falling edges. C. To minimize errors caused by noise at the CS input, the internal circuitry waits for three system clock cycles (or less) after a chip-select falling edge is detected before responding to control input signals. Therefore, no attempt should be made to clock-in address data until the minimum chip-select setup time elapses. 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.
