SN74AXC4T245-Q1: DIR connection double confirm

Part Number: SN74AXC4T245-Q1

Hello team,

My customer want to double confirm whether DIR pin can connected to GND or VREF_A directly?

Do not need to add the res between DIR pin and GND/Power?

I think it is Okay for our IC, but it may need add some Res to protect from the outside? Maybe you can clarify for customer from the system/IC level.

Please recommend the Res value if it is necessary.

Best regards,

Lanxi
