The ST3485ECDR 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. This 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. 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.
Industry standard 75176 pinout
Current limiting and thermal shutdown for driver overload protection
Guaranteed high receiver output state for floating inputs with no signal present
Interoperable with 5V logic
1µA Low current shutdown mode maximum
ESD sensitive device, take proper precaution while handling the device.
