ISO7141CCDBQ

Overview

The ISO7141CCDBQ is a quad-channel digital isolator from Texas Instruments, housed in a 16-pin SSOP package. It provides unidirectional signal isolation with a maximum data rate of 50 Mb/s and an insulation voltage of 2500 Vrms. The device operates on a supply voltage range of 2.7 V to 5 V, drawing a typical quiescent current of 14 mA per channel. Key electrical parameters include a propagation delay of 23 ns and a common-mode transient immunity rating of 25 kV/µs. It supports standard logic interfaces and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides functional isolation for four independent signal channels using capacitive coupling technology.
• Features integrated noise filters to enhance signal integrity in electrically noisy environments.
• Supports high-speed data transmission up to 50 Mbps for efficient communication across isolation barriers.

Applications

• Industrial automation systems requiring galvanic isolation between control units and sensors.
• Medical equipment needing reliable signal separation for patient safety compliance.
• Power electronics interfaces for monitoring and control in motor drives and inverters.

Procurement Notes

Verify the specific suffix 'CC' confirms the standard output configuration and pinout compatibility with your design. Ensure the SSOP-16 footprint matches your PCB layout constraints. Confirm that the 2500 Vrms insulation rating meets the safety requirements of your target application environment. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are needed at moderate speeds. Compare against the ISO7140 series if lower power consumption is prioritized over speed. Consider the ISO7141F variant if a default low output state is required upon power-up. Evaluate thermal dissipation capabilities given the 14 mA per channel operating current.

Part Context

This part belongs to the ISO714x family of general-purpose digital isolators designed for robust performance in industrial applications. It complements other Texas Instruments isolation products by offering a balance of speed and power efficiency in a compact surface-mount package.

Replacement Considerations

The ISO7141CCDBQR is the reel-packaged equivalent of this cut-tape unit. Verify pin-to-pin compatibility before substituting with similar devices from other manufacturers.
