(1)Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods
may degrade device reliability. These are stress ratings only, and
functional operation of the device at these or any other conditions
beyond those specified is not implied.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.

Dual-purpose output:
Data ready: indicates valid data by going low.
Data output: outputs data, MSB first, on the
first rising edge of SCLK.

Serial clock input: clocks out data on the
rising edge. Used to initiate calibration and
Sleep mode (see text for more details).
