ST3485ECDR

ST3485ECDR is a 3.3V powered, 15KV ESD protected, RS-485/ RS-422 transceiver. The transmit and receive 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.

• One driver and one receiver in half duplex configuration
• Operate from a single 3.3V supply - no charge pump required
• Interoperable with 5V logic
• 1µA low current shutdown mode max
• Common mode input voltage range from -7 to 12V
• 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
• Allow up to 64 transceivers on the bus
• 8 lead SO package and temperature range from 0 to 70°C
