Description The MAX3480A/MAX3480B are electrically isolated, RS-485/RS-422 data-communications interface solu- tions. Transceivers, optocouplers, a power driver, and a transformer are in one standard 28-pin DIP package. Signals and power are internally transported across the isolation barrier (Figure 1). Power ...
