SN74AVCH8T245: DIR switching

Part Number: SN74AVCH8T245


Hi experts,

I plan to use this chip as a level converter in my design. It needs to meet the requirements of two-way data transmission and communication speed of about 100MHz. Therefore, it is necessary to switch DIR dynamically. I want to confirm whether the DIR pin can be switched dynamically and what is the switch time parameter.

Thanks

wen

    Hi wen,

    The DIR pin switching characteristics are very similar to the OE pins. You can use them as a reference for the DIR pin as needed. The switching characteristics of OE pin are described in datasheet 7.6~7.10 part.

    Best Regards,

    Amy
