With a maximum data rate of 30Mbit/s, the SN65LBC174ADW provides reliable transmission over long distances

SN65LBC174ADW General Description

The SN65LBC174ADW is a highly capable quad differential line driver specifically designed for transmitting digital signals over long distances in noisy industrial and automotive environments. Its wide common-mode voltage range and high output voltage levels make it well-suited for challenging applications where reliable communication is essential. With a maximum data rate of 20 Mbps and compatibility with RS-485 and RS-422 standards, it provides the performance and versatility required for modern communication systems. The device's four independent drivers with separate enables offer flexibility in controlling each channel individually, catering to applications that demand precise channel management. Moreover, the SN65LBC174ADW is capable of driving up to 32 unit loads, making it an ideal choice for long transmission lines and systems with multiple receivers. It also incorporates essential protection features such as thermal shutdown and short-circuit protection, ensuring continuous and dependable operation in harsh environmental conditions. Housed in a 16-pin SOIC package, it is easy to integrate into existing designs, simplifying the implementation process for engineers and designers
