LTC1487CS8#TR - Ultra-Low Power RS485 Transceiver

The LTC1487CS8#TR is a high-performance RS485/RS422 transceiver from Linear Technology, designed to provide reliable data communication with minimal power consumption. This device is ideal for battery-powered or power-sensitive applications due to its ultra-low power operation and automatic power-saving features.

Enclosed in an 8-lead SOIC package, the LTC1487CS8#TR features a slew rate limited driver which reduces EMI and allows for error-free data transmission up to 250kbps. This makes it an excellent choice for long cable runs and noisy industrial environments where signal integrity is paramount.

Key Features:

• Low Power Consumption: The device operates with a very low supply current of 120µA when unloaded or fully loaded with the driver disabled, and 1µA in shutdown mode, making it one of the most power-efficient transceivers on the market.
• Driver and Receiver Enable: Separate enable pins for the driver and receiver provide additional flexibility and power saving, allowing the transceiver to enter a low-power mode when not in use.
• Thermal Protection: The LTC1487CS8#TR is equipped with thermal shutdown protection, which protects the device from damage due to excessive temperature.
• Failsafe Receiver: The receiver has a failsafe feature that guarantees a high output state under conditions of floating or shorted inputs, enhancing data integrity.
• Extended Temperature Range: This device is specified for operation from -40°C to 85°C, ensuring reliable performance in extreme environments.
