TPT7487-SOBR ISO-RS485-3peak

　　The TPT7487 is a±15 kV IEC61000 ESD protected,3.0 V~5.5 V isolated RS485 transceivers that meet the RS-485 and RS-422 standards for Half Duplex communication.The TPT7488 is isolated Full Duplex RS485.The TPT748x features a fail-safe receiver,which support the output of the receiver to be logic high when the differential input(bus pin A/B)of the receiver is open,short or idle.Transmitters in this family deliver exceptional differential output voltages into the RS-485 required 54Ωload.The 500 kbps device has very low bus currents so they present a true“1/8 unit load”to the RS-485 bus.This allows up to 256 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 are floating,shorted,or on a terminated but undriven bus.The TPT748x is available in WSOP-16 package and is characterized from−40°C to+125°C.
