TXB0108: What is the maximum clock frequency under VCCA=3.3V and VCCB=5V conditions?

 Hello guys,

 One of my customer is considering using TXB0108 for their next products.

 They have the following question.

Q. What is the maximum clock frequency under VCCA=3.3V and VCCB=5V conditions when 50% on duty clock signal is input to TXB0108?

   According to "6.10 Timing Requirements: VCCA = 3.3 V ± 0.3 V" section on page 7, the minimum pulse duration is 10ns.

  So they think the maximum clock frequency is 50MHz. Is it correct?

 Could you please tell me your answer or comment?

 Your reply would be much appreciated.

 Best regards,

 Kazuya Nakai.
