Product details

Three channels, one direction — the isolation you need, no surprises

The ADUM3301ARWZ is a three-channel digital isolator from ADI's iCoupler family, using magnetic coupling to transfer digital signals across a 2500 Vrms isolation barrier. Two channels on side 1 drive signals to side 2; one channel on side 2 drives back to side 1. That fixed direction means you route the data flow before layout — no bidirectional bus on this part. Data rate tops out at 1 Mbps, with 100 ns propagation delay and 40 ns pulse-width distortion, so it fits isolated SPI, UART, or GPIO signals at moderate speeds.

1 Mbps data rate — what it buys you and where it clips

Data rate is 1 Mbps with 100 ns propagation delay.

Isolation rating is 2500 Vrms with common-mode transient immunity of 25 kV/µs.

Temperature range and environment

Package is 16-SOIC wide-body.

Lifecycle and sourcing

It is ROHS3 compliant.

Frequently asked questions

Is ADUM3301ARWZ unidirectional or bidirectional?

Unidirectional. Each channel passes data in one fixed direction: two channels from side 1 to side 2, one channel from side 2 to side 1. There is no bidirectional or direction-switching capability.

What is the data rate of ADUM3301ARWZ?

1 Mbps maximum. Propagation delay is 100 ns typical, pulse-width distortion is 40 ns max.

What are alternatives to ADUM3301ARWZ?

The ADUM1310ARWZ is a three-channel unidirectional isolator with a higher 3750 Vrms isolation rating but otherwise similar 1 Mbps data rate and same package. The ADUM3470ARSZ and ADUM3402ARWZ-RL are four-channel parts in the same iCoupler family — the 3470 has all four inputs on side 1, the 3402 has a 2/2 split. None are drop-in replacements; check channel count and direction before swapping.
