4-channel digital isolator based on the Texas Instruments ISO6540, providing galvanically isolated digital signal transmission at speeds up to 50 Mbps. The module features four forward channels (4/0), functional isolation up to 400 VRMS, independent power supplies for both sides, and can also be used as a logic level shifter. Pololu 5740
Description
The 4-channel digital isolator is designed to provide galvanic isolation between two electronic circuits communicating through digital signals. The module is based on the Texas Instruments ISO6540, enabling data transmission at speeds of up to 50 Mbps on each of the four channels. Galvanic isolation prevents current flow between the two sides, reducing the risk of damage caused by ground potential differences, wiring faults, 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 function as a logic level shifter between circuits operating at different logic voltages. All four channels transmit signals from side 1 to side 2 (4 forward, 0 reverse), and the outputs default to a high state (Default High) if the input signal or supply voltage is lost.
The 2.54 mm pitch through-holes are compatible with standard pin headers and solderless breadboards. The PCB features an isolation slot that increases the creepage distance to 5.3 mm, while the manufacturer specifies a 400 VRMS functional isolation rating. The module is suitable for industrial automation, embedded systems, microcontroller applications, control systems, and any project requiring safe digital communication between galvanically isolated circuits.
