Description:

The ST3485EB/EC/EI/EIY device is ±15 kV ESDprotected, 3.3 V low power transceiver for RS485 and RS-422 communications. The devicecontains one driver and one receiver in halfduplex configuration.The ST3485E device transmits and receives at aguaranteed data rate of at least 12 Mbps.All transmitter outputs and receiver inputs areprotected to ±15 kV IEC 61000-4-2 air discharge.The driver is short-circuit current limited and isprotected against excessive power dissipation bythermal shutdown circuitry that places the driveroutputs into a high impedance state.
