Product Overview
MAX3485AEASA+T is a half duplex, ±20kV ESD-protected RS-485/422 transceiver, optimized for extended cable runs in noisy environments. It has a 1-unit load receiver input impedance, allowing up to 32 transceivers on the bus. This transceiver includes a fail-safe receiver, ensuring the receiver output (RO) is high when inputs are shorted, open, or connected to a three-state bus. It features enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±20kV HBM ESD, ±15kV air-gap ESD and ±8kV contact ESD in accordance to IEC 61000-4-2. It is used in applications such as industrial-control local area networks, transceivers for EMI-sensitive applications, and telecommunications.
- Short-circuit protected outputs, allows up to 128 transceivers on the bus
- Hot-swap capability eliminates false transitions during power-up or hot insertion
- Supply voltage range from 3V to 3.6V, 20Mbps maximum data rate
- Supply current is 1.9mA typical at (VCC = +3.0V to +3.6V), 32 nodes
- Shutdown supply current is 10µA maximum at (VCC = +3.0V to +3.6V)
- Receiver input current is 430µA typical at (VCC = +3.0V to +3.6V)
- Receiver input resistance is 48Kohm minimum at (-7V ≤ VCM ≤ 12V)
- Driver propagation delay is 30ns maximum at (RL = 54ohm, CL = 50pF)
- Receiver propagation delay is 35ns maximum at (CL = 15pF, VCC = +3.3V and TA = +25°C)
- Operating temperature range from -40°C to +125°C, 8-pin SOIC package
