The ISL83491IB is a professional-grade quad receiver IC component designed for RS-422 and RS-485 communication applications. Manufactured by Renesas Electronics, this highly versatile device offers several key features that make it an ideal choice for demanding environments.
One of the primary highlights of the ISL83491IB is its wide common-mode input voltage range, spanning from -7V to +12V. This wide range allows the receiver to operate reliably even in noisy industrial settings where voltage spikes and fluctuations are common, ensuring robust communication links.
Another notable feature of this IC component is its excellent receiver input impedance. With a differential input impedance of 12kΩ and a common-mode input impedance of 100kΩ, the ISL83491IB provides efficient signal reception and high immunity to noise interference.
The ISL83491IB offers a flexible power supply voltage range, from 4.5V to 5.5V, allowing it to integrate seamlessly with various power systems. Additionally, it supports full- and half-duplex operations, enhancing its versatility for a wide range of applications.
This IC component incorporates a unique fail-safe circuitry, enabling a logical high output state when the receiver inputs are open or shorted. This fail-safe feature eliminates the need for external pull-up or pull-down resistors, simplifying the design and reducing component count
