Overview
Description
ISOW1432BDFMR is a dual-channel isolated digital isolator from the ISOW family. It provides galvanic isolation between a logic side (VDD1) and an isolated side (VDD2), allowing a microcontroller or logic circuit to safely interface with high-voltage or noisy environments without a common ground.
Key points:
- Two independent, bidirectional digital channels
- TTL/CMOS-compatible inputs and logic-level outputs
- Separate supply pins for each side (VDD1 and VDD2) with required decoupling
- Built-in isolation barrier rated for a specified high-voltage isolation, plus protection against faults and ESD
- RoHS-compliant package (DFMR marking indicates the package/traceability)
Common applications: industrial controllers, motor drives, power meters, data acquisition systems, and any system requiring signal transfer across an isolation barrier.
How to use: power each side independently, connect the input side to the host logic, the output side to the target logic, and keep the grounds isolated. Follow the datasheet for exact electrical specs, isolation rating, propagation delay, temperature range, and recommended PCB layout.

Pinout
Pin count: 8 pins (8-pin package, e.g., DFMR).
Function: ISOW1432BDFMR is a dual-channel digital isolator that provides galvanic isolation between two sides of a system. It transmits two independent digital signals across an isolation barrier (commonly used to isolate SPI/I/O signals between a host and peripherals) with separate power/ground for each side.
