Frequently Asked Questions
What is the ISO35DW and what does it do?
The ISO35DW is a dual-channel digital isolator from Texas Instruments. It provides galvanic isolation up to 5000 VRMS between two circuit domains while passing digital signals at data rates up to 35 Mbps. It is commonly used to protect microcontrollers from high-voltage transients in industrial and motor control applications.
What package and pin count does the ISO35DW come in?
The ISO35DW is housed in an 8-pin SOIC package with a 1.27 mm pitch. Its compact footprint makes it suitable for space-constrained PCB designs in industrial and medical equipment.
What are common replacements or alternatives to the ISO35DW?
Common alternatives to the ISO35DW include the ADuM1201 from Analog Devices (dual-channel, up to 25 Mbps), the Si8422 from Silicon Labs, and TI's own ISO7221 (up to 150 Mbps). Selection depends on required data rate, isolation voltage, and supply voltage compatibility.
What supply voltage does the ISO35DW require?
The ISO35DW operates on a supply voltage range of 2.25V to 5.5V on both the input and output sides, making it compatible with 3.3V and 5V logic systems. Each side can be powered independently for mixed-voltage designs.
Is the ISO35DW RoHS compliant?
Yes, the ISO35DW is RoHS compliant and lead-free. It meets international environmental regulations for restriction of hazardous substances, making it suitable for consumer electronics, industrial, and medical end products.
