7LB184 Description

Short technical summary and product information.

The SN75LBC184 from Texas Instruments is a differential transceiver designed for RS-485 and RS-422 communication standards. This half-duplex device integrates transient voltage suppression (TVS) for enhanced protection of bus terminals against ESD events, exceeding ±30kV IEC 61000-4-2 contact discharge.

Key electrical characteristics include a maximum signaling rate of 0.25 Mbps and a fault protection range of -15V to 15V. The common-mode voltage range is -7V to 12V, and it supports up to 128 nodes on the bus with a 1/4 unit load. The transceiver features controlled driver output slew rates to allow for longer cable stub lengths and an open-circuit fail-safe receiver design.

Operating within a temperature range of 0°C to 70°C, the SN75LBC184 is available in SOIC and PDIP packages. It includes thermal shutdown protection and power-up/power-down glitch protection, ensuring robust operation in electrically noisy environments. The low disabled supply current of 300 µA maximum makes it suitable for power-sensitive applications.

This transceiver meets or exceeds the requirements of TIA/EIA-485 and ISO/IEC 8482:1993(E) standards, making it a reliable choice for industrial and commercial communication systems.
