3PEAK TPT485N ± 18K ESD Protection, Bus-Polarity Correcting RS-485 Transceiver Features Description  Exceeds Requirements of EIA-485 Standard The TPT485N is a low-power RS-485 transceiver with  Bus-Polarity Correction within 100 ms (tFS) automatic bus-polarity correction and transient protection.  Data Rate: 300 bps to 500 kbps  Works with Two Configurations: Upon hot plug-in, the device detects and corrects the bus polarity within the first 100 ms of bus idling. On-chip transient protection protects the device against IEC61000 – Failsafe Resistors Only ESD and EFT transients. This device has robust drivers – Failsafe and Differential Termination Resistors and receivers for demanding industrial applications. The  Up to 256 Nodes on a Bus (1/8 unit load) bus pins are robust to electrostatic discharge (ESD)  Wide Supply Voltage 3V to 5.5V events, with high levels of protection to Human-Body  SOIC-8 Package for Backward Compatibility Model (HBM), Air-Gap Discharge, and Contact Discharge  Bus-Pin Protection: specifications. The device combines a differential driver and a differential receiver, which operate together from a – ±18 kV HBM protection single 5-V power supply. The driver differential outputs – ±12 kV IEC61000-4-2 Contact Discharge and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. The device features a wide common-mode voltage range making the device suitable for multi-point applications over long cable runs. Applications The TPT485N is available in SOP8 package, and is characterized from –40°C to 125°C.  E-Metering Networks  HVAC Systems  DMX512-Networks 3PEAK and the 3PEAK logo are registered trademarks of 3PEAK INCORPORATED.
