Hi team,
Customer must need 1.8V to 3.3V level shifter on 8bit paralel signal. Since the application is paralel interface the skew ch to ch skew is critical for communication. To consider the switching characteristics, the delays are 4.4ns max, 0.5ns min. That results in 3.9ns which isn't accepted if the variation is channel to channel. It is hoped that this variation is device to device variation.

Please let me know suitable device if it doesn't fit the application.
Regards,
Hayashi
