SN74AXC4T245-Q1: OE, DIR referenced to VCCb?

Part Number: SN74AXC4T245-Q1

Hi team,

The datasheet of SN74AXC4T245-Q1 specifies “The SN74AXC4T245-Q1 device is designed so the control pins (xDIR and x OE) are referenced to VCCA.”

However, I'd like to check if the OE and DIR can be referenced to VCCB without issue at the following condition. Can you answer its?


Condition: VCCA < VCCB

  -. OE pin can be connected to VCCB side?

  -. DIR pin can be connected to VCCB side?
