The LTC491IN is an integrated circuit from Linear Technology designed as a differential driver and receiver pair for RS-485 and RS-422 applications. It operates from a single 5V supply and features a low quiescent current of 300µA typical.
Key electrical characteristics include a wide bus common mode range of -7V to 12V and ±7V ground difference tolerance, allowing for robust communication in noisy environments. The device supports full-duplex operation with one driver and one receiver, capable of data rates up to 2.5 Mbps. It includes features such as thermal shutdown protection and power-up/down glitch-free driver outputs, permitting live insertion or removal.
The LTC491IN is housed in an N-14 package and is suitable for through-hole mounting. Its operating temperature range is from -40°C to 85°C, making it adaptable for various industrial and commercial applications. The transceiver supports up to 32 transceivers on the bus, offering flexibility in network design.
