TPT481 Datasheet | 3PEAK

Features - Exceeds Requirements of EIA-485 Standard - Hot Plug Circuitry - Tx and Rx Outputs Remain Three- State During Power-up/Power-down - Data Rate: 20 Mbps - Up to 256 Nodes on a Bus (1/8 unit load) at 20Mbps - Full Fail-safe Receiver (Open, Short, Terminated) - Wide Supply Voltage 3V to 5.5V - Bus-Pin Protection: ±18 k V HBM ESD ±15 k V IEC61000-4-2 Contact Discharge ±15 k V IEC61000-4-2 Air Discharge - - 40°C to 125°C Operation Temperature Range 3.0V to 5.5V RS-485 Transceivers Description The TPT481 are IEC61000 ESD protected, 3.0V to 5.5V powered transceivers that meet the RS-485 and RS-422 standards for balanced munication. Transmitters in this family deliver exceptional differential output voltages into the RS-485 required 54Ω load. These 20Mbps 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 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. TPT481 is designed for half-duplex RS485, and support SOP8， MSOP8 and DFN3X3-8L package, which is characterized from - 40°C to 125°C.
