Description
The 2-channel digital isolator is designed to provide galvanic isolation between two electronic circuits communicating via digital signals. The module is based on the Texas Instruments ISO6521 integrated circuit, enabling data transmission at speeds of up to 50 Mbps on each of its two channels. Galvanic isolation prevents current flow between the two sides of the circuit, reducing the risk of damage caused by ground potential differences, wiring errors, or electrical noise.
Each side of the isolator is powered independently with a supply voltage from 1.71 V to 5.5 V, allowing the module to also function as a logic level translator between systems operating at different logic voltages. The module provides one communication channel from side 1 to side 2 and one channel from side 2 to side 1 (1 forward, 1 reverse). In the event of input power or signal loss, the outputs default to a logic high state (Default High).
The 2.54 mm pitch through-holes are compatible with standard pin headers and solderless breadboards. The PCB includes an isolation slot that increases the creepage distance to 2.8 mm, while the manufacturer specifies a functional isolation rating of 450 VRMS. The module is suitable for industrial automation, embedded systems, microcontroller-based designs, controllers, and other applications requiring safe signal transmission between galvanically isolated circuits.
