LTC2876/LTC2877, PROFIBUS RS485 Transceivers

Analog Devices’ IEC 61158-2 transceivers for industrial communication in noisy environments

Image of Analog Devices' LTC2876/LTC2877, PROFIBUS RS485 TransceiversAnalog Devices’ LTC2876/LTC2877 are PROFIBUS RS485 transceivers with a supply voltage of 4.5 V to 5.5 V but can operate down to 3 V with reduced supply current. The devices are designed for PROFIBUS-DP master and PROFIBUS-DP slave applications. They are fully compatible with IEC 61158-2, type 3: medium attachment unit (MAU). With operation up to 20 Mbps, the LTC2876/LTC2877 supports all PROFIBUS data rates up to 12 Mbps.

The LTC2876/LTC2877 are exceptionally robust, tolerating ±60 V faults on the bus pins and protected to ±52 kV ESD. These devices are suitable for harsh environments or where 24 V power might be inadvertently connected. Extended ±25 V input common mode range and full fail-safe operation improve data communication reliability in noisy systems.
