Hello
I need advice about rs-485 transciever that can run at 4.5V supply voltage, and cheap.

Thanks.

Hi,

There are manufacturers for those ICs.

Usually they have interactive selection guides on their web pages, where you can select about supply voltage and price.

I presume standard 5V transceivers, although specified only for 4.75 to 5.25 voltage range will work well at 4.5 V.

Cheapest are bipolar devices like SN75176, but they have uncomfortable high quiescent current. My standard general purpose transceiver is CMOS SN75LBC176.
