Product details

Four-channel isolator for industrial signal isolation

The ADUM3402BRWZ-RL is a 4-channel unidirectional digital isolator from the iCoupler series, built with magnetic coupling technology. It provides 2500Vrms isolation across a 16-SOIC package, with a data rate of 10Mbps.

Lifecycle and sourcing

ADI lists this part as Active and ROHS3 compliant. No NRND or EOL notice. For a BOM freeze, this is a safe line item — no imminent LTB risk. Sourced through independent distribution; availability and current pricing confirmed at quote time against an RFQ.

Frequently asked questions

Where can I buy ADUM3402BRWZ-RL?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — stock levels and lead time are confirmed at quote time.

What is the pinout of ADUM3402BRWZ-RL?

The pinout follows the standard 16-SOIC wide-body layout for the ADUM3402 family: pins 1-2 are Side 1 inputs, pins 3-4 are Side 1 outputs, pins 5-8 are Side 1 supply and ground; pins 9-12 are Side 2 supply and ground, pins 13-14 are Side 2 outputs, pins 15-16 are Side 2 inputs. The exact pin mapping is in the ADI datasheet.

Is ADUM3402BRWZ-RL a direct replacement for ADUM3402BRWZ?

Yes — the -RL suffix only denotes Tape & Reel packaging. The die, electrical specs, and package are identical to the tube-shipped ADUM3402BRWZ. It is a direct drop-in replacement.

What is the difference between ADUM3402 and ADUM3401?

The ADUM3402 has a 2/2 channel direction split (two channels each way), while the ADUM3401 has a 3/1 split (three channels one way, one the other). Both share the same 2500Vrms isolation and 10Mbps data rate. Choose the 3402 for bidirectional SPI or UART isolation; choose the 3401 when you need more forward-direction channels.

Can ADUM3402BRWZ-RL isolate I2C signals?

I2C is bidirectional and open-drain; this part is unidirectional with push-pull outputs, so it cannot directly isolate standard I2C without external circuitry (e.g., a separate isolator per direction plus a pull-up on each side). For I2C isolation, consider a dedicated bidirectional isolator like the ADUM1250.
