DescripTion

The LTC^®2876 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/

LTC2877supportsallPROFIBUSdataratesupto12Mbps.

PROFIBUS IEC 61158-2 Compliant

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

TheLTC2876andLTC2877areexceptionallyrobust,toler-

ating 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.

Wide Operating Temperature Range: –40°C to 125°C

Available in Small DFN and MSOP Packages
