SN74AXC8T245: SN74AXC8T245 Internal resistance

Part Number: SN74AXC8T245

Hi Expert,

I would like to check SN74AXC8T245 internal resistance value. I can't find the data from datasheet.

Please help to confirm. One more question, if PCB trace pass thru SN74AXC8T245, could we control trace resistance or it can't be controlled?

Thank you.

  • Hey Bo,

    I'm a little confused by the question, but I will assume you are asking for output impedance and are looking to impedance match (you can correct me if i'm wrong). To know the output impedance I would have to know the supply voltages, but here is an FAQ that walks you through how to calculate worst case out impedance. Here is an FAQ about impedance matching, that should help with the second question.
