Product Summary

The SN65LBC184D is a differential data line transceiver in the trade-standard footprint of the SN75176 with built-in protection against high-energy noise transients. This feature provides a substantial increase in reliability for better immunity to noise transients coupled to the data cable over most existing devices. Use of these circuits provides a reliable low-cost direct-coupled (with no isolation transformer) data line interface without requiring any external components. The SN65LBC184D can withstand overvoltage transients of 400-W peak (typical). The conventional combination wave called out in IEC 61000-4-5 simulates the overvoltage transient and models a unidirectional surge caused by over voltages from switching and secondary lightning transients. The applications of the SN65LBC184D include Industrial Networks, Utility Meters and Motor Control.
