LTC1483CS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1483CS8#TRPBF is an ultra-low power RS-485/RS-422 differential line transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply (4.75V to 5.25V) and supports data rates up to 250 kbits/s. The device features one driver and one receiver in an 8-lead SOIC package. Key electrical parameters include a typical quiescent current of 80µA with the driver disabled, 500µA maximum with the driver enabled, and less than 1mA in shutdown mode. It provides a common-mode range of –7V to 12V, thermal shutdown protection, and I/O pins rated for over –10kV ESD protection.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power CMOS design significantly reduces consumption compared to bipolar counterparts while maintaining ruggedness against overload and ESD damage.
• Controlled slew rate driver decreases electromagnetic interference radiated from RS-485 lines and improves signal fidelity on unterminated lines.
• Thermal shutdown circuit prevents excessive power dissipation caused by bus contention or faults by forcing driver outputs into a high impedance state.
• Receiver includes a fail-safe feature that guarantees a high output state when inputs are left open.

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485 and RS-422 communication systems
• Industrial environments requiring low electromagnetic interference
• Level translation applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging upon procurement. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the ordering information matches the required package type and lead finish specifications provided in the official datasheet.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low power consumption and reduced EMI emissions within the RS-485 standard. It is suitable for systems needing extended common-mode voltage ranges and robust ESD protection. Consider the 250 kbits/s maximum data rate limitation imposed by the controlled slew rate when designing high-speed networks.
