LTC487CSW#TRPBF

The LTC487CSW#TRPBF is a robust interface integrated circuit designed to translate RS232 signals to RS485 levels. Manufactured by Analog Devices Inc., this device integrates four low-power RS485 drivers into a single package. A key design feature is the built-in hysteresis on the receiver inputs, which enhances noise immunity in electrically noisy industrial environments. The component is housed in a 16-Lead Plastic Small Outline (Wide .300 Inch) surface-mount package, facilitating compact PCB layouts. It operates under RoHS3 standards and meets REACH requirements, making it suitable for modern manufacturing compliance. Engineers can utilize this translator for serial communication links requiring reliable half-duplex data transmission over balanced lines.

The integrated hysteresis helps prevent false triggering caused by signal ringing or ground bounce, ensuring stable communication across long cable runs. Its low-power architecture makes it ideal for battery-operated equipment and systems where thermal management is critical. The wide SOIC package allows for standard automated assembly processes while providing adequate spacing for high-voltage isolation if required by the system design.

This part belongs to the LTC487 family, which offers various package and temperature options to suit different deployment scenarios. The TRPBF suffix confirms it ships in tape-and-reel format for efficient surface-mount production. Verify bus termination and biasing networks during implementation to maximize signal integrity and minimize reflections on the RS485 differential pair.
