SN74LVCH16T245: Question about maximum data rate

Dear TI experts,

My customer considers SN74LVCH16T245 for their new product, and they have a question about data rate.

the condition that my customer want is 3.3V input and 1.8V output.

1. I found that SN74LVCH16T245 supports maximum 200MHz under 3.3V input/5V output condition.

How about 3.3V input/1.8V output? what is maximum data rate under this condition?

(they want to use 48MHz clock rate.)

2. Is there any table about maximum data rate regarding to each input voltages and output voltages?

3. SN74LVCH16T245 is released in 2005. my customer is worried about discontinuation.

Could you recommend latest device which can support 48MHz clock speed (or more) and 16bits translation?

Best regards,

Chase
