We can at least point you to a newer replacement for the ABT device.

Can you please share the replacement as per specification?

Hi Albert,

Thanks for your response.

But i am not able to validate the information which is mentioned in the highlighted box.

Can you please help me to validate this in datasheet of SN74AHCT245?

Thanks,

Gaurav

Hi Clemens,

Thanks for your clarifications.

Can we use VMEH22501 in our VME64 design? 

Thanks,

Gaurav
