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?
