Présentation
Description
The device features two independent channels and utilizes silicon dioxide (SiO2) insulation technology, ensuring a high level of reliability and performance. It supports data rates up to 25 Mbps and offers a robust isolation rating of 2500 VRMS. The ISO7220BDR operates over a wide temperature range, typically from -40°C to 125°C, making it suitable for harsh environments.
Its low power consumption and ability to maintain data integrity in noisy environments contribute to its efficiency and effectiveness in isolating digital signals. The device is commonly used in systems where safety and data integrity are critical, ensuring that signal integrity is maintained across isolated domains without direct electrical contact.

7. Fail-Safe Outputs: The outputs go to a high-impedance state when the input supply is below the specified threshold, enhancing safety.
These features make the ISO7220BDR suitable for applications such as industrial automation, motor control, and power supply systems.
Pinout
Here is a concise description of the pin configuration:
1. VCC1 (Pin 1): Power supply for the primary side.
2. GND1 (Pin 2): Ground for the primary side.
3. INA (Pin 3): Data input for channel A.
4. INB (Pin 4): Data input for channel B.
5. OUTB (Pin 5): Data output for channel B.
6. OUTA (Pin 6): Data output for channel A.
7. GND2 (Pin 7): Ground for the secondary side.
8. VCC2 (Pin 8): Power supply for the secondary side.
The ISO7220BDR provides two isolated channels for digital signals, ensuring secure and noise-free communication between different parts of a system, especially where there is a need to separate high and low voltage sections.
