ST485EC - RS-485/RS-422 transceiver

Download the ST485EC datasheet PDF. This datasheet also covers the ST485EB variant, as both devices belong to the same rs-485/rs-422 transceiver family and are provided as variant models within a single manufacturer datasheet.

General Description

Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that place the driver outputs into a high-impedance state.

Key Features

  • Low quiescent current: 300 µA.
  • Designed for RS-485 interface.
