ISO7741DWR Information

Description

The Texas Instruments’ ISO7741DWR is a high-speed, low-power digital isolator that offers robust electromagnetic compatibility (EMC) performance. It features four-channel isolation in a compact 16-pin SOIC package. This device enables fast and reliable data transmission at up to 100 Mbps while providing a rugged and durable design against EMI interference. The ISO7741DWR utilizes silicon-based semiconductors and supports multichannel capability, ensuring data integrity through redundancy. This digital isolator is suitable for high-reliability systems in industrial applications, with a wide operating temperature range of -55°C to 125°C. It also features low power consumption, making it an excellent choice for battery-powered devices. The ISO7741DWR offers a solid solution for designers seeking reliable and efficient data transmission in a variety of industries.

Package

The package type of ISO7741DWR is SOIC (DW)-16, a 16-pin Small Outline Integrated Circuit package.

Pinout

According to the product information, the ISO7741DWR has a package type of SOIC (DW)-16, which indicates that it has 16 pins.

As for the pin function, since this is a digital isolator, it likely has input pins for receiving data and output pins for transmitting data. The exact pinout may vary depending on the specific application and usage. However, based on typical digital isolator designs, I would expect to see:

  • Input pins (e.g., IN1-4) for receiving data from one side
  • Output pins (e.g., OUT1-4) for transmitting data to the other side
  • Power supply pins (e.g., VCC, GND) for powering the device

Please note that this is an educated guess based on general knowledge of digital isolators. For specific information about the pinout and function of ISO7741DWR, I recommend consulting the manufacturer's documentation or datasheet.

Manufacturer

The manufacturer of the ISO7741DWR is Texas Instruments (TI), a leading American technology company that designs, manufactures, tests, and sells semiconductors and other electronic components. TI is a global semiconductor leader with a broad portfolio of innovative technologies and products that include analog and embedded processing, power management, and interface and connectivity solutions.
