SN74AVC4T245: What about the transmission speed at A, B side both are 3.3V?

Part Number: SN74AVC4T245
Other Parts Discussed in Thread: SN74AXC4T245

Dear colleague,

Our customer has a demand: one side is 3.3V, another side is 1.2V/1.8V/3.3V.

So the customer wants to know the speed when A, B side both are 3.3V.

But we can't find this spec in the datasheet.

Best Regards,

Rock Su

See section 6.11 of the datasheet. (worst-case: 1 / 2.9 ns ≈ 345 Mbps)

Hi Rock,

You could consider suggesting SN74AXC4T245 which is P2P to AVC4T245 and supports up to 380Mbps with both sides at 3.3V.

Hi ShreyasRao,

Thanks!

And I have a concern that how to know the transmission speed because I only find the delay specs in the datasheet.

Transmission speed is a very important spec, but many datasheets don't have a clear and direct description.

Best Regards,

Hi Rock Su,

The features section shows the max data rates, but it is not a spec on the electrical characteristics.
