LTC4309CGN#PBF

LTC4309CGN#PBF Description

The LTC4309CGN#PBF from Analog Devices Inc. is a robust 2-channel I²C/SMBus buffer and accelerator designed to enhance signal integrity in multi-master bus systems. Operating within a 2.3V to 5.5V supply range, it supports data rates up to 400kHz, making it ideal for high-speed communication. Housed in a 16-pin SSOP package, this device features hot-swappable capability, enabling live insertion/removal of I²C cards without bus disruption. Its low 10pF input capacitance minimizes loading effects, while the 7mA supply current ensures efficient power consumption. Compliant with ROHS3 and REACH standards, it is suitable for industrial and commercial applications requiring reliable I²C buffering.
