LTC4311CSC6

Signal Buffers, Repeaters, Splitters Overview

The LTC4311CSC6#PBF is a single-channel I2C logic buffer manufactured by Analog Devices Inc. It supports supply voltages ranging from 1.6 V to 5.5 V, accommodating 1.8 V, 2.5 V, 3.3 V, and 5 V logic levels. The device operates within an industrial temperature range of -40°C to +85°C and features a maximum clock frequency of 400 kHz. Packaged in a surface-mount SC-70-6 (SOT-363) format with exposed pad, it draws a typical supply current of 0.3 mA. This component is designed for level translation and signal buffering in I2C and SMBus applications.
