Part Number: SN74AXC4T245-Q1

Dear expert,

Customer use below SN74AXC4T245-Q1 IBIS file from

However, they met below error. Is there any suggestion for them?

  • Hi Ryan,

    The IBIS model only includes models for I/O pins of the device. For the SN74AXC4T245-Q1, GND is just a standard name in IBIS model. GND pin is used as a reference & is not modeled in the IBIS model. Here's an app note that provides further details regarding IBIS models.

    Hope this helps. Thanks!
