Analog Devices (MAX3467ESA+) Transceiver RS422, RS485

Product Overview The MAX3467ESA+ is a +5V, fail-safe, profibus RS485/RS422 transceiver in 8 pin NSOIC package. This high speed and full duplex differential bus transceiver is designed to meet TIA/EIA-422-B, TIA/EIA-485-A, V.11 and X.27 standards. It complies with profibus specification providing +2.1V minimum output level with 54ohm load and 40Mbps data rate. The MAX3467 contains one three state differential line driver and one differential input line receiver. The device operates from +5V supply and feature true fail-safe circuitry which provides logic high receiver output when receiver inputs are open or shorted. This enables all receiver outputs on a terminated bus to output logic highs when all transmitters are disabled. It has 1/4 standard unit load receiver input impedance that allows 128 transceivers on the bus. The driver and receiver has active-high and active-low enables respectively and can be connected together externally to serve as a direction control. It is used in level translators. Supply voltage range from 4.75V to 5.25V Operating temperature range from -40°C to 85°C 15ns transmitter propagation delay and 20ns receiver propagation delay 2ns transmitter and receiver skew Designed for multipoint transmissions on long or noisy bus lines High differential driver output level (2.1V on 54ohm) Low supply current of 2.5mA Current limiting and thermal shutdown for driver overload protection Applications Communications & Networking, Industrial Product Information Device Type: Transceiver IC Interface Type: RS422, RS485 No. of Drivers: 1Drivers No. of Receivers: 1Receivers Supply Voltage Min: 4.75V Supply Voltage Max: 5.25V Driver Case Style: NSOIC No. of Pins: 8Pins Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited IC Generic Number: MAX3467
