SN74AXC4T774-Q1: Propagation delay data across different temp and devices

Part Number: SN74AXC4T774-Q1
Other Parts Discussed in Thread: TXV0106-Q1

Tool/software:

Hi team,

My customer is using this device as 1.8V to 3.3V level shifter for TDM signal. It is sensitive for the propagation delay time. The delay time will have impact on the sampling time.

Below is the schematic from customer. As checked in datasheet, the propagation delay time from A to B and B to A as below.

To make sure the accurate of the TDM data transfer, we would like to check with about the propagation delay time distribution data across high and low temperature(-40C to 125C) and device to device propagation delay matching data. Could you share that?

Thanks!

Hello Ethan,

We don't have this information. During validation, our team captures prop delay at set temperature values

If the customer is interested in faster prop delay values they can look at the TXV0106-Q1

Josh

Hi Josh,

Already shared TXV0106-Q1 with customer. But it is too late for this project to change the solution.

Could you please share that data with me? It will helpful for customer to understand the impact of propagation delay time in their system.

Thanks!

Hello Ethan,

Please allow some time to bring this up with my team and to see if this is something we are able to provide. I should have a response by tomorrow. Thanks.

Regards,

Josh

Hello Ethan,

After discussing with the team, we are only able to guarantee the parameters that appear on our datasheets. Information like prop delay at certain temperatures cannot be provided. Apologies for the inconvenience.

Regards,

Josh
