Product details

Six-channel SPI isolator — what it carries across the barrier

The Maxim Integrated MAX14483AAP+ is a 6-channel digital isolator for SPI buses, using capacitive coupling to pass 25Mbps data across a 3750Vrms isolation barrier.

Timing and transient immunity — the numbers that matter for SPI integrity

Common-mode transient immunity is specified at 50kV/µs typical. That is the figure that matters when the isolator sits between a noisy power stage (motor drive, inverter, SMPS) and a sensitive controller. A fast voltage transient on the isolation barrier will not glitch the data output if the CMTI rating is high enough — and 50kV/µs is well into the robust range for industrial drives.

Frequently asked questions

What is the data rate of MAX14483AAP+?

25Mbps maximum. At this rate, the propagation delay (33.6ns max) consumes most of the bit period, so careful PCB layout and short traces are needed to avoid setup/hold violations on the SPI bus.

Is MAX14483AAP+ compatible with 3.3V systems?

Yes. The supply voltage range is 1.71V to 5.5V, so it operates directly from a 3.3V rail. It also works with 1.8V and 5V logic without level shifters.

What is MAX14483AAP+'s listed type (SPI) on this component line?

It is an SPI digital isolator. The six unidirectional channels are configured as 2 inputs on side 1 and 4 inputs on side 2, which suits SPI (SCLK, MOSI, MISO, CS) plus extra isolated signals.
