ISO7131CCDBQ

Overview

The ISO7131CCDBQ is a triple-channel digital isolator from Texas Instruments, housed in a 16-pin SSOP package. It supports unidirectional data transmission at a maximum signaling rate of 50 Mbps with 5-V supplies. The device provides 2500 Vrms isolation voltage and features capacitive coupling technology. It operates within a supply voltage range of 2.7 V to 5 V, drawing a typical operating current of 10.5 mA. The component exhibits a propagation delay of 23 ns and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Robust design incorporating integrated noise filters for signal integrity
• Low-power operation suitable for energy-efficient applications
• High common-mode transient immunity capability

Applications

• Industrial communication interfaces
• Medical equipment signal isolation
• Power management systems

Procurement Notes

Verify the specific suffix DBQ confirms the SSOP-16 surface-mount package and tube packaging format. Ensure the order matches the unidirectional channel configuration (2 forward, 1 reverse). Confirm RoHS compliance status and humidity sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when three isolated channels are required for unidirectional data transfer. It is appropriate for designs needing 2500 Vrms isolation with low power consumption. Consider the 50 Mbps speed limit and 23 ns delay for timing-critical applications. Verify that the SSOP-16 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ISO7131CC family of general-purpose digital isolators. It serves as a key interface solution for separating high-voltage domains from low-voltage control logic. The series is designed to replace traditional transformer and optocoupler solutions in modern electronic systems requiring reliable galvanic isolation.

Replacement Considerations

Check for ISO7131CCDBQR if reel packaging is preferred over tubes. Evaluate ISO7141CCDBQR for quad-channel requirements. Verify pinout compatibility before substituting with other TI isolator models.
