SN65LBC184D Description

The SN65LBC184D from Texas Instruments is a robust half-duplex RS-422/RS-485 transceiver designed for reliable data communication in industrial and commercial environments. Housed in an 8-pin SOIC package, this surface-mount IC integrates one driver and one receiver, supporting data rates up to 250 kbps. Operating within a 4.75V to 5.25V supply range, it ensures stable performance in noisy conditions, thanks to its 70 mV receiver hysteresis, which enhances noise immunity. The device is RoHS3 compliant and adheres to REACH regulations, making it suitable for environmentally conscious designs.

SN65LBC184D Features

• Half-Duplex Operation: Enables bidirectional communication on a single twisted-pair line, reducing wiring complexity.
• High Noise Immunity: 70 mV receiver hysteresis minimizes errors in electrically noisy environments.
• Wide Supply Range: Operates at 4.75V–5.25V, compatible with standard 5V systems.
• Robust Protocol Support: Compliant with RS-422 and RS-485 standards, ensuring interoperability.
• Industrial Reliability: Mounted in a rugged SOIC package with MSL 1 (Unlimited) moisture sensitivity, ideal for harsh conditions.
• Low Power Consumption: Optimized for energy-efficient designs without sacrificing performance.
