ISO722MDR

Overview

The ISO722MDR is a single-channel high-speed digital isolator from Texas Instruments, designed for 3.3-V and 5-V systems. It supports signaling rates up to 150 Mbps with typical propagation delay of 12 ns and pulse skew of 0.5 ns. The device features capacitive coupling isolation technology and operates within a supply voltage range of 3 V to 5.5 V. It includes a low-power sleep mode and offers a common-mode transient immunity (CMTI) of 25 kV/µs. The component is available in an 8-pin SOIC package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• High-speed data transmission capability supporting up to 150 Mbps signaling rates
• Integrated low-power sleep mode for energy efficiency optimization
• Robust common-mode transient immunity rated at 25 kV/µs

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal interfaces needing high reliability
• Power electronics gate drive circuits

Procurement Notes

Verify the complete part number including suffixes such as 'DR' which indicates tape-and-reel packaging. Confirm that the specific variant matches the required channel count and speed grade. Ensure compatibility with the target system's voltage levels and thermal requirements before procurement.

Selection Notes

Select this component when a single isolated channel with high-speed performance is required. Consider the 150 Mbps rate for applications demanding faster data throughput compared to standard 25 Mbps isolators. Evaluate the 8-SOIC package constraints against board space limitations and thermal dissipation needs.

Part Context

This device belongs to the ISO72x family of digital isolators from Texas Instruments. These components utilize capacitive coupling technology to provide electrical isolation between input and output sides. The family offers various channel counts and speed options to suit different interface requirements in industrial and commercial applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify that any substitute maintains the 150 Mbps data rate and 25 kV/µs CMTI specifications. Ensure the replacement supports the same 3.3-V/5-V supply voltage range.
