ST3485EIDT

ST3485EIDT is a ±15KV ESD protected, 3.3V low-power transceiver for RS-485 and RS-422 communications. This 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. 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, guaranteed 12Mbps data rate
• Industry standard 75176 pinout, -7V to 12V common mode input voltage range
• Current limiting and thermal shutdown for driver overload protection
• Guaranteed high receiver output state for floating inputs with no signal present
• VCC power supply current is 1.3mA typical at (no load, DI = 0V or VCC)
• Shutdown supply current is 1µA maximum at (DE = 0V, RE = VCC, DI = 0V or VCC)
• Propagation delay is 18ns typical at (RL= 27 ohm, CL = 15pF)
• Receiver input resistance is 24Kohm minimum at (VCM = -7V to 12V)
• Operating temperature range from -40°C to 125°C, S08 package
