SN74AXC4T774-Q1: SN74AXC4T774-Q1 IBIS model

Part Number: SN74AXC4T774-Q1

Tool/software:

Hi Team,

Using the level shifter, we are simulating an SPI interface which translates from 3.3V to 1.8V. @20Mhz

The waveforms at the output of Level shifter seems to be improper.

The signal low seems to be dipping to -0.5V using the IBIS model from the TI website.

And also, this occurs only at Slow corner of the simulation alone.

Please do provide your comments on this.

Thanks and regards,
