Maxim Integrated (MAX3072EESA+) +3.3V, RS485/RS-422 Transceivers

Product Overview The MAX3072EESA+ is a ±15kV ESD-protected, fail-safe, hot-swap, RS-485/RS-422 Transceiver. This device includes fail-safe circuitry, guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic high if all transmitters on a terminated bus are disabled (high impedance). The MAX3072EESA+ include a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion. The MAX3072E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX3073E also feature slew rate-limited drivers but allow transmit speeds up to 500kbps. The MAX3072E is intended for half-duplex communications. The MAX3072EESA+ transceiver draw 800µA of supply current when unloaded or when fully loaded with the drivers disabled. All devices have a 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus. Hot-swap input structure on DE and RE-bar Enhanced slew-rate limiting facilitates error-free data transmission Allows up to 256 transceivers on the bus Applications Lighting, Automation & Process Control, Industrial, Communications & Networking, Security, Sensing & Instrumentation Product Information Device Type: Transceiver IC Interface Type: RS422, RS485 No. of Drivers: 1Drivers No. of Receivers: 1Receivers Supply Voltage Min: 2.97V Supply Voltage Max: 3.63V Driver Case Style: SOIC No. of Pins: 8Pins Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
