3PEAK TP8485E ± 18K ESD Protection, Full Fail-Safe RS-485 Transceiver Features Description  Exceeds Requirements of EIA-485 Standard The TP8485E are IEC61000 ESD protected, 3V~5.5V  Hot Plug Circuitry - Tx and Rx Outputs Remain powered transceivers that meet the RS-485 and RS-422 Three-State During Power-up/Power-down standards for balanced communication. Driver outputs and receiver inputs are protected against ±18kV ESD  Data Rate: 300 bps to 250 kbps  Full Fail-safe (Open, Short, Terminated) Transmitters in this family deliver exceptional differential Receivers output voltages (2.5V min/5Vcc), into the RS-485 required  Up to 256 Nodes on a Bus (1/8 unit load) 54Ω load, for better noise immunity, or to allow up to eight  Wide Supply Voltage 3V to 5.5V 120Ω terminations in “star” topologies. These devices  SOIC-8 Package for Backward Compatibility have very low bus currents so they present a true “1/8 unit  Bus-Pin Protection: strikes without latch-up. load” to the RS-485 bus. This allows up to 256 transceivers on the network without using repeaters. – ±18 kV HBM protection Receiver (Rx) inputs feature a “Full Fail-Safe” design, – ±13 kV IEC61000-4-2 Contact Discharge which ensures a logic high Rx output if Rx inputs are – +4 kV IEC61000-4-4 Fast Transient Burst floating, shorted, or on a terminated but undriven bus. Rx Applications outputs feature high drive levels - typically 25mA @ VOL = 1V (to ease the design of optocoupled isolated  E-Metering Networks interfaces).  Industrial Automation The TP8485E is available in an SOIC-8 and MSOP-8  HVAC Systems package, and is characterized from –40°C to 125°C.  Process Control  DMX512-Networks  Battery-Powered Applications 3PEAK and the 3PEAK logo are registered trademarks of 3PEAK INCORPORATED.
