Dear team

There is a good news that we design in SN74AXC4T245BQBR in customer's new project.

Could you help to review the schematic?

Many thanks

Hey Denny,

Everything looks good. I would recommend the 100K pull-ups be switched to 10K. The glitch suppression circuitry acts as a weak pull-down that could contend with larger resistors.

Hi Dylan

I would recommend the 100K pull-ups be switched to 10K.

=> They change R9813 from 100kohm to 10kohm as the attached file. Could you help to double confirm the schematic?

The glitch suppression circuitry acts as a weak pull-down that could contend with larger resistors.

=> Dose the schematic need to change any component? The schematic have modified as below.

Many thanks

Denny

Hey Denny,

The updated schematic looks good, I see no changes needed.
