ADUM7642CRQZ

Overview

The ADUM7642CRQZ is a six-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 1000 Vrms isolation voltage with a data rate of 25 Mb/s and common-mode transient immunity of 15 kV/µs. The device operates on a 3 V to 5.5 V supply, drawing 19 mA or 31 mA depending on configuration. Propagation delay is typically 14 ns with rise/fall times of 2.8 ns. It features bidirectional channels in a 20-lead QSOP package, operating between -40°C and +105°C.

Feature Summary

• Six independent signal paths for high-density channel isolation
• Integrated magnetic coupling eliminates external transformer requirements
• Bidirectional data transmission capability across all channels

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal interface circuits
• Power electronics gate drive isolation

Procurement Notes

Verify the specific suffix (e.g., CRQZ) against the datasheet to confirm the package type and temperature range. Ensure the order matches the required channel configuration and isolation voltage ratings for the target application environment.

Selection Notes

Select this component when six isolated channels are required within a single package footprint. Compare propagation delay and power consumption against other iCoupler variants if lower latency or reduced current draw is critical for the system design.

Part Context

This part belongs to the ADUM764x series of general-purpose digital isolators from Analog Devices. It shares the core iCoupler architecture with similar parts like the ADUM7641, differing primarily in channel count and directionality configurations.

Replacement Considerations

The ADUM7642CRQZ-RL7 is the reel-pack equivalent of the tube-packed ADUM7642CRQZ. Both share identical electrical specifications and pinouts.
