Electrical characteristics

(1) Parameters are given by selecting 10 MHz I/O output frequency.

(2) Data characterization in progress.

(3) Values based on design simulation and/or characterization results, and not tested in

production.

(4) Min time is for the minimum time to drive the output and the max time is for the maximum

time to validate the data.

(5) Min time is for the minimum time to invalidate the output and the max time is for the

maximum time to put the data in Hi-Z.
