Analog Devices (MAX3073EESD+) Transceiver RS422, RS485

Product Overview The MAX3073EESD+ is a ±15KV ESD protected, fail-safe, hot swap RS485/RS422 transceiver in 14 pin NSOIC package. This 3.3V transceiver has one driver and one receiver. It includes fail-safe circuitry which provides logic high receiver output when receiver inputs are open or shorted. The receiver provides logic high if all transmitters on a terminated bus are disabled (high impedance). The device includes a hot swap capability to eliminate false transitions on the bus during power-up or hot insertion. The MAX3073E has slew rate limited drivers but allow transmit speeds up to 500Kbps. This transceivers draw 800µA of supply current when unloaded or when fully loaded with the drivers disabled. The transceiver has 1/8 unit load receiver input impedance allowing up to 256 transceivers on the bus. It is typically used in lighting systems. Supply voltage range from 2.97V to 3.63V Operating temperature range from -40°C to 85°C Intended for full duplex communications Ease of design and robust performance ±15KV human body model ESD on I/O pins True fail-safe receiver while maintaining EIA/TIA-485 compatibility 10µA shutdown current mode for power savings Receiver/driver enable function Applications Communications & Networking, Industrial, 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: NSOIC No. of Pins: 14Pins Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
