Features
- The SN65LBC184DR is a high-performance RS-485 transceiver designed for robust communication in electrically challenging environments. It integrates several advanced features to enhance reliability and functionality:
- Enhanced ESD and Surge Protection:

- The SN65LBC184DR includes integrated transient voltage suppressors that protect against Electrostatic Discharges (ESD) up to ±30 kV according to IEC 61000-4-2 and surge transients up to 400 W peak per IEC 61000-4-5.This increases dependability under challenging conditions and provides strong protection against electrical disruptions.
- Controlled Slew Rate for Data Transmission:
- The device features slew-rate controlled differential drivers that enable reliable data transmission up to 250 kbps. The controlled output voltage transitions allow for longer unterminated cable runs and extended stub lengths from the main cable trunk, making it suitable for electrically noisy environments.
- Fail-Safe Receiver Design:
- The receiver incorporates a unique design that provides a high-level failsafe output when the inputs are left floating. By preventing communication mistakes, this feature guarantees dependable communication even in the absence of a valid input signal.
- Thermal and Power-Up/Down Protection:
- This model has power-up/power-down glitch protection to keep stability during voltage changes and thermal shutdown protection to guard against overheating damage. These precautions enhance the dependability and durability of the equipment.
Package information
- The 8-SOIC package that the SN65LBC184DR is packaged in is appropriate for surface mounting.The product is 1.75 mm tall, 3.91 mm wide, and 4.9 mm long. Its thickness is 1.58 mm. With a basic quantity of 2500 units per reel, each product is supplied in tape-and-reel packaging and weighs roughly 72.6 mg. This kind of packaging guarantees automated placement during assembly and effective handling.
