We use a lot of RS485 in our industrial controller operations. Most apps use 8-pin SOIC, 5V, Vcc/Gnd/TxD/RxD/TE/~RE/A/B. They cost about a buck.
I'm working on a new board that will use a 3.xV processor. I thought it would be straightforward to find a corresponding RS485 transceiver that operates on 3V-5V; or failing that at 3.xV. Yes, I'm finding some, but not many and not for a buck or two.
Am I searching incorrectly? Or any other suggestions?
