STMicroelectronics ST3485 series Drivers Interface ICs

The ST3485 series is a ±15 kV ESD protected, 3.3 V low power transceiver for RS-485 and RS-422 communications. These devices contain one driver and one receiver in half duplex configuration. These devices transmit and receive at a guaranteed data rate of at least 12 Mbps. All transmitter outputs and receiver inputs are protected to ±15 kV IEC 61000-4-2 air discharge. The driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high impedance state.
