MAXIM INTEGRATED / ANALOG DEVICES MAX3491AEASD RS-485 Transceiver
The MAX3491AEASD is a high-speed RS-485/RS-422 transceiver designed for reliable differential data communication over long cable runs in noisy industrial and telecommunication environments. Powered at 3.3V, it offers robust +20kV ESD protection (HBM) and supports data rates up to 20Mbps with slew-rate limiting for signal integrity. Features include fail-safe receivers that output high when inputs are shorted or open, hot-swap capability to prevent false bus transitions during power-up, and a wide operating temperature range from -40°C to +125°C, making it ideal for industrial control, telecommunications, and sensor networks.
