SN74AVC8T245: power up/down sequence

Part Number: SN74AVC8T245

Hello,

 

My customer uses SN74AVC8T245PW as follows.

 

Case #1

OE and DIR are connected to GND (Data direction is always B to A)

Vcca=1.8V

Vccb=3.3V

 

Case #2

OE and DIR are connected to GND (Data direction is always B to A)

Vcca=3.3.V

Vccb=1.8V

 

For those two cases, are there any power up/down sequence they have to follow?

Or Vcca and Vccb power up/down could be any orders?

 

Best regards,

 

K.Hirano
