SN65HVD266D TI RS-485 Transceiver | 8-SOIC | 3.3V, 250kbps, Half-Duplex

Product Overview

The SN65HVD266D from Texas Instruments is a robust half-duplex RS-485 transceiver designed for industrial communication networks. Operating from a 3.3V supply, it delivers data rates up to 250 kbps while featuring enhanced electrostatic discharge (ESD) protection up to ±16 kV (HBM). The device is housed in an 8-pin SOIC package, making it suitable for space-constrained applications. Its differential bus architecture ensures reliable data transmission over long cable runs in noisy environments.
