Product Description
ADM3490ARZ-REEL7 - 3.3V Half-Duplex RS-485/RS-422 Transceiver IC
A low-power 3.3V half-duplex RS-485/RS-422 transceiver IC designed for robust industrial communication with minimal power consumption.
Key Features
-
Half-Duplex RS-485/RS-422 CommunicationIntegrates a single driver and receiver for bidirectional data transfer over a shared differential bus, eliminating separate transmit/receive lines in half-duplex architectures.
-
Low Power OperationFeatures low quiescent current (typically 300 μA) in active mode and power-down mode reducing supply current to less than 0.1 μA, ideal for battery-powered applications.
-
Robust ESD ProtectionProvides ±15 kV electrostatic discharge protection on RS-485 bus pins, meeting IEC 61000-4-2 standards for enhanced reliability in industrial environments.
-
Wide Common-Mode Voltage RangeOperates with -7V to +12V common-mode voltage range, supporting long cable lengths and systems with significant ground potential differences.
-
Driver Slew-Rate ControlIncorporates controlled slew-rate driver to minimize EMI and reduce signal reflections, enabling data rates up to 500 kbps without external components.
-
Receiver Input SensitivityDetects differential input voltages as low as ±200 mV, ensuring reliable data reception in noisy industrial environments.
