RS-485 is an electrical standard that specifies the electrical characteristics of driver and receiver circuits for balanced data transmission over multipoint data networks. For loss-of-signal (LOS) ...

TI's Thomas Kugelstadt offers a number of technical fixes for RS-485 bus signal polarity correction (POLCOR) in industrial control systems. POLCOR used to be rare. Now, it results ...

RS-485 has a wide operating voltage range, from an Rx threshold of 200mV to a maximum differential signal of 10V. Usually 2V P-P is the minimum recommended drive level, and 3.3V devices will meet that ...

Robustness and reliability have made RS-485 an industrial workhorse. A minimum differential signal swing of 1.5V and reliable operation over common-mode voltages ranging from -7V to +12V have ...

A typical RS-485 network has several nodes, each with a differential driver and receiver (Fig. 1). The twisted-pair bus is terminated with the characteristic impedance at each end of the bus line.

Texas Instruments has releases an RS-485 transceiver that can be pin-programmed to suit networks with different bus voltage, logic voltage, network length and throughput. Called THVD1424, it includes ...

Intersil has introduced the ISL3259E RS-485/RS-422 transceiver, an interface IC that combines fast data transmission rate (100Mbps) with a low 2.6mA supply current and rugged 15kV IEC61000-4-2 ESD ...

The LTC 4671 Series are Transceivers designed especially for the transmission of RS-485 signals used by system keyboards in the Allegiant Series of switcher/ controller systems, the Divar Series of ...

MaxLinear, Inc., a technology leader transforming global connectivity, announced today the launch of a new family of RS-485 serial transceivers specifically designed to ensure reliable ...
