The TPT7481 is a ±15-kV IEC61000 ESD protected, 3.0-V~ 5.5-V isolated RS485 transceivers that meet the RS-485and RS-422 standards for Half Duplex communication.The TPT7482 is isolated Full Duplex RS485.The TPT748x features a fail-safe receiver, which supportsthe output of the receiver to be logic high when thedifferential input (bus pin A/B) of the receiver is open,short, or idle.Transmitters in this family deliver exceptional differentialoutput voltages into the RS-485 required 54-Ω load. The20-Mbps device has very low bus currents, so they presenta true “1/8 unit load” to the RS-485 bus. This allows up to256 transceivers on the network without using repeaters.Receiver (Rx) inputs feature a “Full Fail-Safe” design,which ensures a logic-high Rx output if Rx inputs arefloating, shorted, or on a terminated but undriven bus.The TPT748x is available in the WSOP16 package and ischaracterized from −40°C to +125°C.
