The LTC2876 and LTC2877 are PROFIBUS RS485 transceivers designed to meet the test specifications for PROFIBUS-DP masters and PROFIBUS-DP slaves, fully compatible with IEC 61158-2, type 3: medium attachment unit (MAU). With operation up to 20Mbps, the LTC2876/ LTC2877 supports all PROFIBUS data rates up to 12Mbps.

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

The LTC2876 and LTC2877 meet PROFIBUS and RS485 specifications with a supply voltage of 4.5V to 5.5V but can operate down to 3V with reduced supply current.
