ST3485EBDR Datasheet PDF - ST Microelectronics

The ST3485EBDR is a 3.3V Low Power Transceiver for RS-485 and RS-422 communications. The device contains one driver and one receiver in half duplex configuration. The device transmits and receives at a guaranteed data rate of at least 12Mbps. All transmitter outputs and receiver inputs are protected to ±15kV 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.

● Operate from a single 3.3V supply - no charge pump required

● Interoperable with 5V logic

● Half duplex versions available

● Industry standard 75176 pin-out

● Current limiting and thermal shutdown for driver overload protection

● Guaranteed high receiver output state for floating inputs with no signal present

● Allow up to 64 transceivers on the bus

● 1µA Maximum low current shutdown mode

● -7 to 12V Common-mode input voltage range
