TPT486/488
3.3V & 5.0V Full Duplex RS-485 Transceivers
Description
The TPT486/488 is IEC61000 ESD protected, which support ±12 k V IEC contact and ±15 k V IEC air discharge. 3.0V ~ 5.5V transceivers that meet the RS-485 and RS-422 standards for Full Duplex munication. Transmitters in this family deliver exceptional differential output voltages into the RS-485 required 54Ω load. The devices have very low bus currents so they present a true “1/8 unit load” to the RS-485 bus. This allows up to 256 transceivers...
