Frequently asked questions
Will ADM489ABRZ drop into a board originally specified for ADM488ABRZ?
The ADM488ABRZ is a full-duplex sibling with the same 250 kbps data rate, 4.5 V minimum supply, 70 mV hysteresis, and 14-SOIC package — the two are pin-compatible and functionally interchangeable in most RS-485/RS-422 circuits without a board spin.
