ADUM7642CRQZ-RL7

Overview

The ADUM7642CRQZ-RL7 is a six-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 1000 Vrms isolation voltage with a common-mode transient immunity of 15 kV/µs. The device supports data rates up to 25 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. Key electrical parameters include a propagation delay of 14 ns, rise/fall times of 2.8 ns, and a pulse width distortion of 40 ns. It functions in temperatures from -40°C to +105°C and is housed in a 20-QSOP package.

Feature Summary

• Six independent digital channels for high-density signal isolation
• iCoupler magnetic coupling technology eliminates transformer limitations
• High common-mode transient immunity for noisy environments
• Bidirectional signal transmission capability

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy monitoring
• Inverter motor drives

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the QSOP-20 package dimensions against your PCB footprint requirements. Ensure the 1000 Vrms isolation rating meets your system's safety standards. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when six isolated channels are required in a compact form factor. The 25 Mb/s data rate suits moderate-speed digital communication. Consider the 15 kV/µs CMTI for applications with high dv/dt noise. Verify power consumption specifications against thermal constraints in enclosed enclosures.

Part Context

This part belongs to the ADUM7642 series of general-purpose digital isolators. It represents Analog Devices' implementation of silicon-based isolation technology. The series offers alternatives to traditional optocouplers with improved performance consistency and lower power consumption.

Replacement Considerations

Check for direct pin-compatible substitutes within the ADUM764x family. Verify that alternative parts maintain the same 20-QSOP package and 1000 Vrms isolation rating. Ensure functional equivalence regarding channel count and data speed before substitution.
