Product Description
STMicroelectronics presents the ST490ABDR line transceiver, a differential transceiver IC housed in an 8-pin SOIC surface mount package. This device is engineered primarily for RS-485 line drivers and receivers, ensuring robust and reliable communication on differential bus systems commonly used in industrial and communication applications.
The ST490ABDR operates within a supply voltage range of 4.5 V to 5.5 V, drawing a low supply current of 5 mA which contributes to efficient power usage. It supports a differential input and output configuration, providing enhanced noise immunity and allowing for error-free data transmission over twisted-pair cables in electrically noisy environments.
Designed with a single channel configuration, this transceiver manages data transmission and reception in RS-485 network systems. It offers maximum high and low level output currents of 8 mA each, capable of driving loads with high reliability. The device delivers fast response with a maximum propagation delay time of 30 ns at the rated load capacitance, suitable for high-speed data applications.
The operating temperature range spans from -40°C to 85°C, ensuring durability under harsh industrial conditions. The package dimensions are 9.8 mm length, 8.8 mm width, and 3.3 mm height, making it compact and easy to integrate in dense PCB assemblies.
Compliance with ECOPACK and JEDEC JESD97 standards guarantees environmental compliance and packaging quality. The ST490ABDR transceiver is an ideal choice for applications in industrial automation, building management systems, instrumentation, and other communication or control systems that require reliable differential line transceivers.
