Overview
The ISL33003IRTZ-T is a dual-channel I2C bus buffer manufactured by Renesas Electronics. It operates within a supply voltage range of +2.3V to +5.5V and supports data rates exceeding 400kHz. The device extends bus capacitance beyond the standard 400pF limit and includes rise time accelerators to improve performance on passive pull-up networks. It features hot-swap capability to protect against damage during insertion into live backplanes and provides logic level translation for mixed-voltage applications. Operating temperatures range from -40°C to +85°C, and it is housed in an 8-pin TDFN package.
Feature Summary
- Dual-channel buffering with integrated rise time acceleration
- Hot-swap protection for safe insertion into powered systems
- Logic level translation for mixed-voltage environments
Applications
- I2C bus expansion and capacitance buffering
- Server rack isolation in telecommunications and data communication
- Desktop computer peripheral interfacing
- Hot-swappable circuit board insertion
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level requirements before assembly. Check for specific manufacturing date codes or lot traceability if required by quality standards. Ensure proper ESD handling procedures are followed during storage and installation.
Selection Notes
Select this component when extending I2C bus capacitance beyond 400pF is necessary. Choose this part for designs requiring hot-swap functionality without external protection circuits. Consider this IC for mixed-voltage systems needing automatic level translation between different power domains.
Part Context
This component belongs to the ISL3300x series of I2C bus buffers. It shares functional similarities with the ISL33002 but offers specific packaging and tape-and-reel configuration options suitable for automated surface-mount assembly processes.
Replacement Considerations
The ISL33003IUZ serves as a pin-compatible alternative in MSOP-8 packaging. Verify that any substitute maintains identical electrical characteristics and thermal performance specifications.
