ISO7720DW

Overview

The ISO7720DW is a high-speed, robust EMC reinforced dual-channel digital isolator from Texas Instruments. It features capacitive coupling technology with a 5000 Vrms insulation voltage and supports data rates up to 100 Mb/s. The device operates within a supply voltage range of 2.25 V to 5.5 V, drawing 11.6 mA of quiescent current. It exhibits a propagation delay of 17 ns and pulse width distortion of 500 ps. The component is housed in a 16-pin SOIC package and functions unidirectionally across an operating temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced electrical isolation for safety-critical applications using capacitive coupling technology.
• Ensures signal integrity in noisy environments through robust electromagnetic compatibility design.
• Supports high-speed data transmission with low propagation delay and minimal pulse width distortion.

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages
• Medical equipment needing reinforced isolation for patient safety compliance
• Power metering circuits isolating high-voltage sensing from low-voltage processing

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure the procurement source provides valid RoHS compliance information. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit components. Confirm that the delivered units match the specified SOIC-16 footprint and pinout configuration required by the design.

Selection Notes
