SN65C3221EPWR – TEXAS INSTRUMENTS

The Texas Instruments SN65C3221EPWR is a single-channel, low-power, RS-485 transceiver designed for robust half-duplex communication in industrial and automotive applications. Operating from a 2.7V to 5.5V supply voltage range, it features a ±15kV ESD protection on all pins, ensuring reliability in harsh environments. The device incorporates a receiver with a high common-mode voltage range of -7V to +12V, enabling interference rejection in noisy industrial settings. Its driver section delivers a ±5V output swing, guaranteeing sufficient signal strength for long cable runs._x000D_
