ISO1540DR is a high-performance digital isolator designed for applications requiring high-speed data transmission and high-voltage isolation. It uses capacitive coupling technology to achieve insulation between the input and output through a silicon dioxide (SiO₂) barrier, ensuring signal integrity and reliability.

ISO1540DR Features

Capacitive coupling technology: Achieves insulation between input and output through capacitance, ensuring signal integrity and reliability.

I²C interface compatibility: Supports bidirectional I²C communication, suitable for sensor control, data acquisition, and communication systems.

High-voltage isolation: Features 2500Vrms voltage isolation capability, ensuring safe use in high-voltage environments.

High common-mode transient immunity: Reaches 25kV/µs, enhancing interference resistance in harsh electromagnetic environments.  

High-speed data transmission: Data transmission rate up to 1Mbps, suitable for real-time data processing and control applications.  

Wide operating temperature range: -40°C to +125°C, suitable for various application environments.

Low power consumption design: Typical power consumption is only 3.5mW, suitable for low power consumption applications.

Bidirectional channel design: Supports 2 input channels and 2 output channels, providing flexibility.

Pulse width distortion control: Maximum 80ns, ensuring signal timing accuracy.

Wide supply voltage range: 3V to 5.5V, highly compatible.

Surface-mount package: Uses an 8-SOIC package for easy automated production.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
