ISO7142CCDBQ

Overview

The ISO7142CCDBQ is a low-power, quad-channel digital isolator from Texas Instruments, housed in a 16-pin SSOP package. It features unidirectional signal transmission with a data rate of 50 Mb/s and an insulation voltage of 2500 Vrms using capacitive coupling. The device operates on a supply voltage between 2.7 V and 5 V, drawing a typical working current of 2.5 mA. It exhibits a propagation delay of 21 ns and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides four independent unidirectional channels for signal isolation
• Utilizes capacitive coupling technology for high-speed data transmission
• Designed for low power consumption with minimal supply current requirements

Applications

• Isolated communication interfaces in industrial automation systems
• Power delivery monitoring circuits requiring galvanic isolation
• Embedded control systems needing reliable signal separation

Procurement Notes

Verify the specific suffix 'DBQ' indicates the standard SSOP-16 package configuration. Confirm that the component meets RoHS compliance standards as listed in official documentation. Ensure the operating environment remains within the specified thermal limits to maintain performance integrity. Cross-reference the datasheet revision to ensure compatibility with design specifications.

Selection Notes

Select this component when four unidirectional isolated channels are required in a compact form factor. It is suitable for applications prioritizing low power consumption alongside moderate data rates. Consider the SSOP-16 footprint constraints during PCB layout planning. Evaluate the 2500 Vrms insulation rating against system safety requirements.

Part Context

This part belongs to the ISO714x family of digital isolators, which emphasizes small footprint and low power characteristics. It serves as a specialized interface solution for separating noisy digital environments from sensitive control logic. The series supports various channel configurations to meet diverse isolation needs.

Replacement Considerations

The ISO7140CCDBQ offers similar isolation capabilities but may differ in specific electrical parameters or channel configurations. Verify pinout compatibility and functional equivalence before substitution. Consult official replacement guides to ensure no loss of performance metrics.
