Product Summary
The 75L6P41-M4 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 75L6P41-M4 provides a reliable low cost direct-coupled (with no isolation transformer) data line interface without requiring any external components. The 75L6P41-M4 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 overvoltages from switching and secondary lightning transients.
