SN65HVD21P TI RS-485 Transceiver | 8-PDIP | 3.3V, 32Mbps

Product Overview

The SN65HVD21P from Texas Instruments is a robust RS-485/RS-422 transceiver designed for balanced data transmission in industrial environments. Housed in an 8-pin PDIP package, it operates from a single 3.3V supply and delivers data rates up to 32 Mbps. The device features a differential output voltage of ±1.5V (min) and a receiver input sensitivity of ±200 mV, ensuring reliable communication over long cable runs. With extended temperature range (-40°C to +85°C) and built-in protection against electrostatic discharge (ESD) up to ±15 kV (HBM), the SN65HVD21P is ideal for harsh industrial applications.
