FAQs

What is SI8641AB-B-IS?

The SI8641AB-B-IS is a quad-channel, digital isolator designed by Silicon Labs. It is ideal for applications requiring signal isolation, such as industrial automation, medical devices, and isolated interface circuits.

How Does SI8641AB-B-IS Work?

The SI8641AB-B-IS works by providing high-speed and robust isolation between two independent systems. It uses a combination of silicon dioxide insulation barrier and integrated CMOS technology to transmit digital signals across the isolation boundary. The isolator offers high noise immunity and low power consumption, making it suitable for demanding industrial environments.

How Many Pins does SI8641AB-B-IS have and What are the Functions of the Pinout Configuration?

The SI8641AB-B-IS is housed in a 16-lead SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VDD1, VDD2: Power supply pins for the input side and the output side, respectively.
  • GND1, GND2: Ground pins for the input side and the output side, respectively.
  • IN1, IN2, IN3, IN4: Input pins for each channel.
  • OUT1, OUT2, OUT3, OUT4: Output pins for each channel.

What are the Pros and Cons of SI8641AB-B-IS?
