LTC4312IMS#PBF

LTC4312IMS#PBF Description

The LTC4312IMS#PBF from Analog Devices Inc. is a high-performance I²C/SMBus buffer and multiplexer designed for hot-swappable applications. Housed in a compact 16-MSOP package, this active component ensures robust signal integrity in multi-master I²C systems. Operating within a 2.9V to 5.5V supply range, it supports data rates up to 400kHz, making it suitable for high-speed communication protocols. With a 1 x 1:2 channel configuration, it enables seamless switching between I²C buses while maintaining low input capacitance (20 pF) to minimize signal degradation. Its 7.3mA supply current ensures efficient power consumption, and its ROHS3 compliance aligns with environmental standards.
