Part Number: SN74LVC244A

Hello expert,

Are we able to enhance output driving capability in SN74LVC244APWR IBIS model? Based on datasheet, output driving capability is related to VCC. Could we adjust VCC in IBIS model? If no, do we have other method to adjust it? Thanks a lot!

Best regards,

Ann Lien
