SN74AVC8T245: Output channel-to-channel skew

Shunsuke Yamamoto

Part Number: SN74AVC8T245
Other Parts Discussed in Thread: TXV0108

Tool/software:

Hi team,

My customer plans to use SN74AVC8T245 for the level translation of 1.5V<->1.8V and 1.8V<->1.5V. Output channel-to-channel skew of them are not stated on the datasheet, so could you please kindly let me know the output channel-to-channel skew of 1.5V<->1.8V and 1.5V<->1.8V. Both min/max value or typical value are acceptable.

This data comes from TXV0108.

Best regards,

Shunsuke Yamamoto

Hello Yamamoto-san,

I see you also contacted us via email with a similar question. To avoid having multiple E2E threads, could we continue our conversation via email? Thanks!

Josh

Hello Yamamoto-san,

Sure we can keep this thread open. I can get AVC8T skew measurements for you.

Hello Yamamoto-san,

Quick update: The EVM I initially used did not provide great skew measurements. Mainly it is the EVM not being optimized for high speed signals. I'll be switching to the AVC8T245-RHL package and use the TVX-EVM instead. Apologies for the delay.

Regards,

Josh

Hello Yamamoto-san,

Please see AVC8T245 output channel-to-channel skew measurements. Values below use C_load = 9pF and are captured at 100MHz and 25ºC

1.5V -> 1.8V

Skew = 483ps

1.8V -> 1.5V

Skew = 528ps

Josh
