ADUM3402TRWZ-EP

Overview

The ADUM3402TRWZ-EP is a quad-channel digital isolator utilizing iCoupler technology. It features four independent channels with a 1/2 input-to-output configuration. The device supports data rates up to 10 Mbps and offers a common-mode transient immunity of 25 kV/µs. Electrical specifications include a supply voltage range of 3.135 V to 5.5 V, maximum propagation delay of 50 ns, and typical rise/fall times of 2.5 ns. It operates within an extended temperature range of -55°C to 125°C and is housed in a 16-SOIC package.

Feature Summary

• Quad-channel isolation with 1/2 channel configuration
• High common-mode transient immunity of 25 kV/µs
• Extended industrial operating temperature range
• Enhanced system-level ESD reliability

Applications

• Automotive electronic control units
• Industrial communication interfaces
• Medical equipment signal isolation
• Power monitoring systems

Procurement Notes

Verify the specific suffix 'EP' indicates enhanced performance or automotive qualification status compared to standard variants. Confirm the manufacturer's datasheet for the ADuM340xW series to ensure all electrical parameters match design requirements. Check for RoHS compliance and moisture sensitivity levels before integration into production workflows.

Selection Notes

Select this component when bidirectional isolation is not required, as it utilizes a unidirectional channel architecture. Ensure the application demands high common-mode transient immunity exceeding standard isolator capabilities. Verify that the 16-SOIC footprint fits the PCB layout constraints and that the extended temperature range meets environmental conditions.

Part Context

This part belongs to the ADuM340x family of iCoupler digital isolators from Analog Devices. It shares the same core magnetic coupling technology as the ADUM3400 and ADUM3401 but differs in channel directionality. The 'EP' suffix typically denotes enhanced product specifications or specific qualification standards distinct from the standard commercial grade parts.

Replacement Considerations

The ADUM3402BRWZ is a compatible alternative within the same family. Verify if the standard temperature range (-40°C to 105°C) suffices for the application, as the EP variant offers extended range. Ensure the unidirectional channel configuration matches the circuit design needs.
