ISL33002IRTZ-T

Signal Buffers, Repeaters, Splitters Overview

The ISL33002IRTZ-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 reduce passive pull-up resistor power consumption. Key electrical parameters include an accelerator trigger voltage of 0.3V, accelerator current of 10mA, and offset voltage (VOS) of 45mV. Typical operating supply current is 2.2µA, with low static current at 2.1mA and shutdown current at 0.5µA. It provides ±6kV Class 3 HBM ESD protection on all pins and ±12kV on SDA/SCL lines. The component is housed in an 8-pin TDFN package measuring 3.0mm x 3.0mm x 0.75mm with a 0.5mm pitch.
