LTC4314CGN#PBF

Signal Buffers, Repeaters, Splitters Overview

The LTC4314CGN#PBF is a pin-selectable, 4-channel, 2-wire bus multiplexer with bidirectional buffers. It allows one upstream bus to connect to any combination of downstream busses or channels via individual enable pins. The device provides capacitance buffering, isolating upstream bus capacitance from downstream loads. It supports level translation between 1.5V, 1.8V, 2.5V, 3.3V, and 5V busses. Electrical specifications include an input supply voltage range of 2.9V to 5.5V, an output side accelerator supply voltage of 2.25V to 5.5V, and an input supply current of up to 9mA when enabled. The component operates within a temperature range of 0°C to 70°C and is housed in a 20-lead plastic SSOP package.
