The LTC2873HUFD#PBF from Analog Devices is a versatile multiprotocol transceiver designed for robust communication on a single 3V to 5.5V supply. It supports both RS232 and RS485 protocols, allowing for flexible interface configurations. The device can operate as a half-duplex RS485 transceiver or an RS232 transceiver using the same two bus pins.
Key electrical specifications include RS485 operation up to 20Mbps and selectable RS232 data rates of 1Mbps or 250kbps. It features integrated termination resistors for both RS485 (120Ω) and RS232 (5kΩ), simplifying design by eliminating external components. The transceiver boasts high ESD protection of ±26kV HBM and RS485 receiver failsafe operation.
This transceiver is available in a 24-pin QFN package (4mm x 5mm) with surface mount mounting type. The operating temperature range is -40°C to 125°C, making it suitable for industrial applications. The integrated DC/DC boost converter eliminates the need for multiple supplies when driving RS232 levels.
Applications include industrial sensors and actuators, alarm systems, traffic control and monitoring, and highway signs and jumbo displays. The device supports up to 256 RS485 nodes per bus.
