Part Number: SN74AXC8T245

Hi team,

Our customer is wondering what's the channel to channel tpd tolerance of SN74AXC8T245 when 1.8V VCCA and 1.8V VCCB. The datasheet doesn't show this value. thanks.

BR.

Hi Wiky,

Is this not the info you are looking for?

Hi Dylan,

No. Customer application is RMGII application, they care about the delay between different channels. For example, at the same environment, if channel A1_>B1 tpd is 1ns, channel A2_>B2 tpd is 6ns, the signal will have 5ns delay between B1 and B2. They need to check if it can meet timing RMGII requirement.

The channel-to-channel skew is less than 1 ns. See [FAQ] What is the difference in timing between gates in the same device? How much skew is expected within a given logic device?
