ISO722DR

Overview

The ISO722DR is a high-speed digital isolator from Texas Instruments, featuring one channel of data transmission. It operates with single-supply voltages of 3.3 V or 5 V and provides an isolation rating of 2500 Vrms. The device supports data rates up to 100 Mbps and offers a common-mode transient immunity of 25 kV/µs. Packaged in an 8-pin SOIC format, it functions within a temperature range of -40 °C to +125 °C.

Feature Summary

• Utilizes capacitive coupling technology for signal isolation
• Provides high common-mode transient immunity
• Supports high-speed data transmission rates

Applications

• Industrial communication interfaces
• Isolated gate drive circuits
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when ordering. Confirm that the required isolation voltage and data rate align with system specifications. Ensure compatibility with 3.3 V or 5 V logic levels. Check for RoHS compliance status if required by project standards.

Selection Notes

Select this component when a single-channel isolator with high speed is needed. Consider the 2500 Vrms isolation barrier for safety requirements. Evaluate the 100 Mbps data rate against bandwidth needs. The wide operating temperature range suits harsh environments.

Part Context

This part belongs to the ISO72x family of general-purpose digital isolators. It serves as a compact solution for replacing traditional optocouplers in space-constrained designs. The series emphasizes low power consumption and high reliability for industrial applications.

Replacement Considerations

Check datasheets for equivalent parts like ISO7221D or ISO7222D for multi-channel needs. Verify pinout compatibility before substitution. Ensure isolation ratings meet or exceed original design requirements.
