Part Details

PROFIBUS IEC 61158-2 Compliant
Protected from Overvoltage Line Faults to ±60V
±52kV ESD Interface Pins, ±15kV All Other Pins
±2kV (Level 4) IEC61000-4-4 Fast Transient Burst
±25V Working Common Mode Range
20Mbps Maximum Baud Rate
1.65V to 5.5V Logic Supply Pin for Flexible Digital Interfacing (LTC2877)

5V Supply Can Operate Down to 3V for Low Power, Low Swing Applications
Fully Balanced Differential Receiver Thresholds with 240mV Hysteresis for Superior Noise Tolerance and Low Duty Cycle Distortion
Receiver Failsafe for Open, Shorted and Terminated Conditions
Wide Operating Temperature Range: –40°C to 125°C
Available in Small DFN and MSOP Packages

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 failsafe 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.
