ISL33002IRTZ

Signal Buffers, Repeaters, Splitters Overview

The ISL33002IRTZ is a dual-channel I2C-compatible bidirectional bus buffer manufactured by Renesas Electronics Corporation. 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 an accelerator trigger voltage of 0.3V with an accelerator current of 10mA. It features low static current of 2.2µA (typical) and hot-swap capability for safe insertion into live backplanes. The component provides ±6kV Class 3 HBM ESD protection on all pins, with ±12kV HBM protection specifically on SDA/SCL lines. It is housed in an 8-lead TDFN package measuring 3.0mm x 3.0mm x 0.75mm with a 0.5mm pitch.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. The 'IRT2Z' designation indicates an active status with a TDFN-EP-8 package supplied in tubes. Confirm moisture sensitivity level and lead-free compliance details directly with authorized distributors prior to procurement to ensure alignment with assembly requirements.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designs require extending I2C bus capacitance beyond standard limits while maintaining high-speed performance up to 400kHz. The integrated rise time accelerator makes it suitable for applications needing reduced power consumption on passive pull-ups. Ensure the operating environment falls within the specified -40°C to +85°C temperature range and that the supply voltage remains between 2.3V and 5.5V.
