Part number : 6LB184
Functions : Differential Transceiver With Transient Voltage Suppression
Manufacturer : Texas Instruments
The SN75LBC184 and SN65LBC184 are differential data line transceivers 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 SN75LBC184 and SN65LBC184 can with stand 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 overvoltages from switching and secondary lightning transients.
