SN65HVD3088ED

The SN65HVD3088ED from Texas Instruments is a half-duplex transceiver specifically designed for RS-485 data bus networks. It operates with a 5-V supply and is fully compliant with the TIA/EIA-485A standard, making it suitable for reliable data transmission over long twisted-pair cables.

This transceiver boasts a maximum signaling rate of 20 Mbps, making it ideal for applications requiring high-speed communication. It supports up to 256 nodes on a single bus, offering significant scalability for complex networks. The device features a wide common-mode range of -7 V to 12 V and fault protection from -9 V to 14 V, ensuring reliable operation in demanding environments.

Designed for power-sensitive applications, the SN65HVD3088ED exhibits low quiescent power consumption, drawing only 0.3 mA in active mode and dropping to 1 nA in shutdown mode. It also includes bus-pin ESD protection up to 15 kV and a fail-safe receiver for bus open, shorted, or idle conditions. The transceiver is available in SOIC, SOP, and VSSOP packages, all suitable for surface mount assembly.

Key features include its compliance with the TIA/EIA-485A standard, low active and shutdown supply currents, and high ESD protection. The controlled transition times are beneficial for long cable transmissions. Its fail-safe receiver and glitch-free power-up/down ensure data integrity.
