The ISO1540DR is a high-performance, low-power, bidirectional I2C isolator produced by Texas Instruments. This product is designed to improve the performance and reliability of systems that require data isolation. It is particularly ideal for applications that require isolation to protect against ground potential differences and noise coupling. The ISO1540DR is a two-channel device that provides bidirectional communication between two I2C buses, with one channel transferring data from the input side to the output side and the other channel transferring data in the opposite direction. This bidirectional communication capability makes it an excellent choice for applications that require simultaneous data transmission in both directions. One of the key features of the ISO1540DR is its high isolation voltage. It can withstand up to 2500 Vrms of isolation voltage, making it perfect for applications that require high voltage isolation. This product also has a wide operating temperature range of -40°C to 125°C, which allows it to function effectively in various environmental conditions. The ISO1540DR also features Texas Instruments' patented noise-filtering technology. This technology helps to reduce the effects of noise coupling, which can often lead to data corruption in systems that require data isolation. With this feature, the ISO1540DR can provide reliable data transmission even in noisy environments. In terms of power consumption, the ISO1540DR is a low-power device. It operates with a supply voltage range of 3.0 V to 5.5 V, which makes it compatible with a wide range of power supply systems. This low-power operation makes the ISO1540DR a great choice for battery-powered applications or applications that require energy efficiency. The ISO1540DR is available in an 8-pin SOIC package, which makes it easy to integrate into various system designs. Its small footprint and high integration level make it a space-saving solution for systems that require data isolation. In conclusion, the ISO1540DR from Texas Instruments is a high-performance, low-power, bidirectional I2C isolator that is designed to improve the performance and reliability of systems that require data isolation. Its high isolation voltage, wide operating temperature range, patented noise-filtering technology, and low-power operation make it an excellent choice for a wide range of applications.
