TPT487 3.0V to 5.5V RS-485 Transceivers Description Features The TPT487 are IEC61000 ESD protected, 3.0V to 5.5V ⚫ Exceeds Requirements of EIA-485 Standard ⚫ Hot Plug Circuitry - Tx and Rx Outputs Remain Three- powered transceivers that meet the RS-485 and RS-422 standards for balanced communication. State During Power-up/Power-down Transmitters in this family deliver exceptional differential output ⚫ Data Rate: 500 Kbps ⚫ Up to 256 Nodes on a Bus (1/8 unit load) at 500kbps ⚫ Full Fail-safe Receiver (Open, Short, Terminated) ⚫ Wide Supply Voltage 3V to 5.5V on the network without using repeaters. Receiver (Rx) inputs ⚫ Bus-Pin Protection: feature a “Full Fail-Safe” design, which ensures a logic high Rx ⚫ 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. This allows up to 256 transceivers ±18 kV HBM ESD output if Rx inputs are floating, shorted, or on a terminated but ±15 kV IEC61000-4-2 Contact Discharge undriven bus. ±18 kV IEC61000-4-2 Air Discharge TPT487 is designed for half-duplex RS485, and support SOP8， –40°C to 125°C Operation Temperature Range MSOP8 and DFN3X3-8L package, which is characterized from –40°C to 125°C.
