ISL33002IUZ-T

Signal Buffers, Repeaters, Splitters Overview

The ISL33002IUZ-T is a dual-channel I2C-compatible bidirectional 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 an accelerator trigger threshold of 0.3V with an accelerator current of 10mA. Typical supply current is 2.2µA, while typical quiescent current is 2.1mA. It features ±6kV Class 3 HBM ESD protection on all pins and ±12kV HBM protection on SDA/SCL lines. The component is housed in an 8-pin MSOP package (3.0mm x 3.0mm) with a pitch of 0.7mm, suitable for industrial temperatures from -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging format required for automated assembly processes. Confirm that the MSOP-8 package dimensions align with the target PCB footprint. Ensure the industrial temperature grade meets the operational environment requirements. Check RoHS compliance status against current regulatory standards. Validate pinout compatibility with existing schematic designs before finalizing procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when design requirements exceed the 400pF I2C capacitance specification or necessitate hot-swap functionality. The integrated rise time accelerator is optimal for reducing power dissipation in passive pull-up configurations. Verify that the operating voltage range covers both the source and destination logic levels for effective level shifting. Consider the low static current specifications for battery-sensitive or energy-efficient system architectures.
