The device combines a differential driver and differential receiver operating from a single 3.3 V supply, with internally connected driver outputs and receiver inputs forming a bus port for two-wire half-duplex communication. It supports data rates up to 20 Mbps with a wide common-mode voltage range of -7 V to +12 V for multi-point applications over long cable runs. The bus pins provide high-level ESD protection to \u00b112 kV IEC 61000-4-2 contact discharge and \u00b14 kV IEC 61000-4-4 fast transient burst. Receiver hysteresis of 80 mV ensures reliable data reception in noisy environments.","working_principle":"The SN65HVD75DR integrates a differential driver and receiver with shared bus pins for half-duplex operation. (1) Driver Section: The driver converts single-ended TTL\/CMOS logic (D input) into differential RS-485 signals (A, B) with controlled slew rate for 20 Mbps operation. The driver output is enabled by the DE pin and features short-circuit current limiting (\u00b1160 mA) and thermal shutdown at 170\u00b0C. (2) Receiver Section: The receiver detects differential signals above the threshold (VIT+ = -20 mV, VIT- = -150 mV) with 80 mV hysteresis, converting them to single-ended logic at the R output. The receiver is enabled by pulling RE low. (3) Bus Protection: Integrated ESD clamps on A and B pins protect against IEC 61000-4-2 contact discharge up to \u00b112 kV and HBM up to \u00b115 kV. Fault protection covers -13 V to +16.5 V on the bus pins. (4) Power Management: In standby mode (DE low, RE high), supply current drops below 2 \u03bcA. Active quiescent current is less than 1 mA.","pin_description":"
