Product details

What this isolator does and where it fits

The Maxim Integrated MAX14932BASE+ is a 4-channel, unidirectional digital isolator using capacitive coupling technology. It provides galvanic isolation up to 2750Vrms between two sides of a circuit, with a data rate of 25Mbps. The part is housed in a 16-SOIC package and operates over the full industrial temperature range of -40°C to 125°C. Typical applications include isolating SPI, UART, or general-purpose digital signals in industrial automation, motor drives, power supplies, and medical equipment where noise immunity and safety isolation are required.

Key ratings and what they mean for your BOM

The 25Mbps data rate handles most common serial interfaces. The 2750Vrms isolation rating is typical for reinforced isolation in industrial environments.

Frequently asked questions

Is MAX14932BASE+ RoHS compliant?

Yes, the MAX14932BASE+ is ROHS3 compliant.

Can MAX14932BASE+ be used for I2C isolation?

I2C is a bidirectional open-drain bus, and the MAX14932BASE+ has unidirectional channels. For I2C isolation you need a part with bidirectional channels or external circuitry to handle the bus direction. This part is better suited for SPI, UART, or GPIO isolation.

What is the pinout of MAX14932BASE+?

The pinout follows the standard 16-SOIC layout for Maxim's 4-channel isolators. Side 1 inputs are on pins 2 and 3; side 2 inputs on pins 10 and 11. Outputs are on the opposite sides. Refer to the datasheet for the full pin map.
