ISO7810FDWW

Overview

The ISO7810FDWW is a single-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC (DWW) package. It operates with a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 100 Mb/s. The device features capacitive coupling isolation with a maximum insulation voltage of 5700 Vrms. Key electrical parameters include a propagation delay of 10.7 ns, rise and fall times of 3.9 ns, and a typical operating supply current of 5.7 mA. It functions within an extended temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced high-voltage isolation via capacitive coupling technology for signal integrity across isolated boundaries.
• Supports unidirectional data transmission at speeds up to 100 Mb/s with low propagation delay.
• Operates reliably across an extended industrial temperature range without requiring external shutdown control.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors
• Medical equipment interfaces needing high-reliability signal separation
• Power electronics gate drive circuits for inverter and converter control

Procurement Notes

Verify the specific suffix FDWW corresponds to the SOIC-16 wide-body package configuration. Confirm RoHS compliance status and humidity sensitivity level prior to PCB assembly planning. Ensure the ordering part number matches the required channel count and polarity specifications for the target design.

Selection Notes

Select this component when a single unidirectional channel with high common-mode transient immunity is required. Compare against other ISO78xx variants based on channel count and bidirectional needs. Verify that the 5700 Vrms insulation rating meets the safety standards of the application environment.

Part Context

This device belongs to the ISO78xx family of high-performance digital isolators. It shares the same core isolation architecture as dual, triple, and quad-channel variants like the ISO7820 and ISO7840. The primary distinction lies in its single-channel configuration, offering a compact solution for applications requiring only one isolated signal path.

Replacement Considerations

Direct functional substitutes within the same series include ISO7810DW and ISO7810DR. For pin-compatible alternatives with different channel counts, consider ISO7820 or ISO7840 families, ensuring voltage and speed requirements are met.
