Product Summary

The SN65LBC184DR 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 the SN65LBC184DR provides a reliable low-costdirect-coupled (with no isolation transformer) data line interface without requiring any external components. The applications of the SN65LBC184DR include Industrial Networks, Utility Meters, and Motor Control.
