The ST485A is a low power, high-speed transceiver designed for RS-485 and RS-422 communications, featuring a half-duplex configuration with one driver and one receiver. It operates over a temperature range of -40 to 85 ¬8C and requires a single 5 V supply, drawing a maximum supply current of 5 mA. The device supports data rates exceeding 30 Mbps and is suitable for multipoint bus transmission lines. Key features include a common mode input voltage range of -7 to 12 V, ¬±4 kV ESD protection, and built-in current limiting and thermal shutdown for driver overload protection. The receiver includes a fail-safe feature that ensures a logic high output when both inputs are open circuit. The ST485A is available in both DIP-8 and SO-8 packages, making it versatile for various applications.
