The accelerator function pulls up the rising edge faster than a passive pull-up resistor, allowing a higher total bus capacitance while staying within the 400 kHz timing budget. Supply current is 5.1 mA typical, which is the quiescent draw when the bus is idle — the dynamic current during data transmission adds a small pulse per edge. RoHS3 compliant (ROHS3 Compliant), suitable for EU and global markets requiring the latest RoHS exemption list.","metaTitle":"LTC4300A-2IMS8#PBF I²C Hot-Swap Buffer, 400 kHz, 8-MSOP","metaDescription":"Analog Devices LTC4300A-2IMS8#PBF I²C hot-swap buffer/accelerator, 2.7-5.5 V supply, 400 kHz data rate, -40 to 85°C, 8-MSOP.
