2.2 Pin descriptions
CMD, Command is a bidirectional line. The host and card drivers are operating in
push-pull.
DAT0-3, Data lines are bi-directional lines. Host and card drivers are operating in
push-pull mode.
CLK, Clock is a host to card signal. CLK operates in push-pull mode.
Feedback (return) Clock is feedback clock signal from level shifter to host for
controlling delays.

3 Electrical ratings
Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
