SN65ALS176DR

The SN65ALS176DR is a differential bus transceiver manufactured by Texas Instruments, designed for robust communication in demanding environments. It operates at data rates up to 35 Mbaud and supports both RS422 and RS485 protocols, making it versatile for various industrial and communication applications.

This transceiver features a half-duplex configuration, with one transmitter and one receiver. It operates within a supply voltage range of 4.75V to 5.25V and maintains functionality across an industrial temperature range of -40°C to 85°C. Key electrical characteristics include a common-mode voltage range of -7V to 12V and receiver hysteresis of 60 mV, contributing to reliable signal integrity.

The SN65ALS176DR is housed in an 8-SOIC package, suitable for surface mounting. Its design includes features such as thermal shutdown protection, driver current limiting, and receiver open-circuit fail-safe operation, enhancing its durability and performance in multipoint transmission scenarios on long bus lines.

This component meets or exceeds the requirements of TIA/EIA-422-B and TIA/EIA-485-A standards, ensuring compatibility with industry-defined communication protocols. Its low supply current requirement of 30 mA max further adds to its efficiency.
