ST3485EBDR

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
