SN65HVD21D TI RS-485 Transceiver | 8-SOIC | 3.3V, 32Mbps

Product Overview

The SN65HVD21D from Texas Instruments is a robust RS-485/RS-422 transceiver designed for balanced data transmission in industrial and automotive applications. Operating from a 3.3V supply, it delivers data rates up to 32 Mbps while maintaining low power consumption. The device features a differential output voltage of 1.5V minimum and a receiver input sensitivity of ±200 mV, ensuring reliable communication over long cable runs. Housed in an 8-pin SOIC package, it is ideal for space-constrained designs.
