Product Summary
The SN75LBC184DR is a differential data line transceiver in the trade-standard footprint of the SN75176 with built-in protection against high-energy noise transients. The SN75LBC184DR features 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. Applications include Industrial Networks, Utility Meters and Motor Control.
