TPT487 Overview
The TPT487 are IEC61000 ESD protected, 3.0V to 5.5V powered transceivers that meet the RS-485 and RS-422 standards for balanced munication. Transmitters in this family deliver exceptional differential output voltages into the RS-485 required 54Ω load. These 500kbps devices have very low bus currents so they present a true “1/8 unit load” to the RS-485 bus.
