Overview
The ISO7220BDR is a dual-channel digital isolator manufactured by Texas Instruments, utilizing capacitive coupling technology for signal transmission. It features two unidirectional channels with a data rate of 5 Mbps and an isolation voltage of 2500 Vrms. The device operates within a supply voltage range of 3V to 5.5V and supports a common-mode transient immunity of 25 kV/µs. Maximum propagation delay is 70ns with a pulse width distortion of 3ns. It functions in temperatures from -40°C to 125°C and is housed in an 8-SOIC package.
Feature Summary
- Provides galvanic isolation between circuits using high-speed capacitive coupling technology.
- Supports bidirectional signal isolation with two independent unidirectional channels.
- Ensures signal integrity under high electromagnetic interference with high common-mode transient immunity.
Applications
- Industrial automation systems requiring isolated communication interfaces
- Medical equipment needing safe patient isolation barriers
- Power electronics control circuits for gate drive isolation
Procurement Notes
Verify the specific suffix 'BDR' confirms the SOIC-8 package and tape-and-reel quantity. Confirm RoHS compliance status matches current regulatory requirements. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement specifications.
Selection Notes
Select this component when a dual-channel solution with 5 Mbps speed and 2500 Vrms isolation is required. Compare against ISO6720BDR if higher 50 Mbps speed or 5000 Vrms isolation is needed. Ensure the 8-SOIC footprint fits the PCB layout constraints and that the 3V-5.5V supply range matches the system power design.
Part Context
This part belongs to the ISO722x family of general-purpose digital isolators from Texas Instruments. It shares the same core architecture as the ISO7221 and ISO7220A but offers optimized performance characteristics for standard industrial applications. The family provides a scalable solution for various isolation needs within the same package form factor.
