The SN65LBC184P is a transient voltage suppression 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 direct-coupled (with no isolation transformer) data line interface without requiring any external components. It can withstand over-voltage transients of 400W peak (typical). The conventional combination wave called out in IEC 61000-4-5 simulates the over-voltage transient and models unidirectional surge caused by over-voltages from switching and secondary lightning transients.
