MAX3221: MAX3221 ENA pin floating

Part Number: MAX3221

Hi Team,

My customer would like to replace MAX3226 with MAX3221. They are not using the READY pin in MAX3226 so it is floating. However, in MAX3221, this pin is /ENA. Is the /ENA pin in MAX3221 with any pull down resistor so that we could leave this pin floating? Or we still need to externally pull this pin to low to enable the Rx channel?

Regards,
