TPT75176A RS-485 Transceivers

3PEAK’s TPT75176A/B is enhanced RS485 which exceeds standard TIA/EIA-485-A with±12kV ESD Protected,3.0~5.5V powered,single transceiver for balanced communication.It also features the larger output voltage and higher data rate-up to 10Mbps-required by high speed PROFIBUS applications,and is offered in Industrial and Extended Industrial(-40°C to+125°C)temperature ranges.This transceiver requires a 3V~5.5V tolerance supply,and delivers at least a 2.1V differential output voltage on 5V supply condition.This translates into better noise immunity(data integrity),longer reach,or the ability to drive up to three 120Ωterminations in“star”or other non-standard bus topologies,at the exceptional 10Mbps data rate.Receiver(Rx)inputs feature a“Full Fail-Safe”design,which ensures a logic high Rx output if Rx inputs are floating,shorted,or terminated but undriven.Rx outputs feature high drive levels(typically>25mA VOL=1V)to ease the design of optically isolated interfaces.The TPT75176A/B is available in an SOP8,MSOP8 and DFN3X3-8L package,and is characterized from–40°C to 125°C.
