SN65LBC184DR Description

Short technical summary and product information.

The SN65LBC184DR is a half-duplex transceiver designed for RS-485 and RS-422 communication interfaces. Manufactured by Texas Instruments, this component offers robust performance with integrated transient voltage suppression (TVS) for enhanced protection.

 

Key electrical specifications include a signaling rate of up to 250kbps, a common-mode voltage range of -7V to 12V, and fault protection from -15V to 15V. It supports a supply voltage range of 4.75V to 5.25V and can accommodate up to 128 nodes on the bus. The receiver hysteresis is 70mV, ensuring reliable signal detection.

 

This transceiver is housed in an 8-SOIC package and is designed for surface mounting. The operating temperature range is -40°C to 85°C, making it suitable for various industrial and commercial applications. The device meets or exceeds TIA/EIA-485 and ISO/IEC 8482 standards.

 

Features such as controlled driver output-voltage slew rates allow for longer cable stub lengths, and the open-circuit fail-safe receiver design enhances system reliability. The SN65LBC184DR also includes thermal shutdown protection and power-up/power-down glitch protection.
