Details
for the ISO1042The ISO1042 device is a galvanically-isolated controllerarea network (CAN) transceiver that meets the specifications of the ISO11898-2 (2016) standard. TheISO1042 device offers ±70-V DC bus fault protection and ±30-Vcommon-mode voltage range. The device supports up to 5-Mbps data rate in CAN FD mode allowing muchfaster transfer of payload compared to classic CAN. This device uses a silicon dioxide(SiO2) insulation barrier with a withstand voltage of 5000VRMS and a working voltage of 1060 VRMS.Electromagnetic compatibility has been significantly enhanced to enable system-level ESD, EFT,surge, and emissions compliance. Used in conjunction with isolated power supplies, the deviceprotects against high voltage, and prevents noise currents from the bus from entering the localground. The ISO1042 device is available for both basic andreinforced isolation (see Reinforced and Basic Isolation Options). TheISO1042 device supports a wide ambient temperature range of –40°Cto +125°C. The device is available in the SOIC-16 (DW) package and a smaller SOIC-8 (DWV)package.

FAQs
What is ISO1042BDWR?
The ISO1042BDWR is a high-speed, reinforced dual-channel digital isolator manufactured by Texas Instruments. It is designed to provide galvanic isolation and signal transmission between two electrical circuits, making it ideal for applications requiring noise immunity, voltage isolation, and data integrity.
How Does ISO1042BDWR Work?
The ISO1042BDWR functions by using internal transformers and capacitors to transmit digital signals across isolation barriers. It isolates the input and output channels electrically while allowing data communication to occur without direct electrical connections, ensuring safety and reliability in noisy industrial environments.
How Many Pins does ISO1042BDWR have and What are the Functions of the Pinout Configuration?
The ISO1042BDWR is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VEE, VCC2: Power supply pins for channel 1 and channel 2 respectively.
- GND1, GND2: Ground pins for channel 1 and channel 2 respectively.
- IN1A, IN1B: Isolated input pins for channel 1.
- OUT1A, OUT1B: Isolated output pins for channel 1.
- IN2A, IN2B: Isolated input pins for channel 2.
- OUT2A, OUT2B: Isolated output pins for channel 2.
What are the Pros and Cons of ISO1042BDWR?
Pros:
- High-Speed Operation: Suitable for applications requiring high-speed data transmission.
- Reinforced Isolation: Provides robust galvanic isolation for enhanced safety.
- Compact Package: The 16-pin SOIC package offers space-efficient integration.
- Wide Temperature Range: Operates over a wide temperature range, suitable for industrial environments.
- Low Power Consumption: Supports energy-efficient operation.
Cons:
- Cost: High-speed digital isolators like the ISO1042BDWR may have a higher cost compared to lower-speed alternatives.
- Complexity: Requires careful consideration of isolation ratings and system compatibility.
- External Components: Additional components may be needed for proper signal conditioning and protection.
Are There Any Equivalents/Alternatives to ISO1042BDWR for Recommendation?
- The ISOW7841 from Texas Instruments is a similar dual-channel digital isolator with integrated power.
- Alternatives to the ISO1042BDWR include the Si823x series from Silicon Labs and the ADUM140x from Analog Devices.
