This document describes the features and characteristics of the SLLS563B model, which is an optimized half-duplex differential transceiver for PROFIBUS networks. It meets the requirements of EN 50170 and TIA/EIA-485-A standards, supports signaling rates up to 40 Mbps, and has features such as low bus capacitance and short-circuit current limit.
The SLLS563B series includes the SN65HVD1176 and SN75HVD1176 PROFIBUS RS‑485 transceivers, optimized for PROFIBUS networks and general RS‑485 applications. They provide differential output voltages exceeding 2.1 V, low bus capacitance, and support up to 160 devices on a single bus with failsafe receiver functionality.
The datasheet specifies electrical parameters such as a signaling rate up to 40 Mbps, supply voltage 4.75‑5.25 V, and operating temperature ranges of –40 °C to 85 °C (SN65HVD1176) and 0 °C to 70 °C (SN75HVD1176). Mechanical dimensions, absolute maximum ratings, and protection features like ESD and thermal shutdown are also included.
