Description: Fast dual bidirectional bus buffer

Features

* Dual, bidirectional unity gain buffer
* Fast switching times allow operation in excess of 1 MHz
* Supports I2C-bus (Standard-mode and Fast-mode), SMBus (standard and high power mode), PMBus and IPMB
* Enable allows bus segments to be disconnected
* Low standby current when not

Applications

* including I2C-bus, SMBus, PMBus, and other systems based on similar principles. The buffer extends the bus load limit by buffering both the SCL and SDA lines. It supports up to 400 pF loads on each side of the buffer at 400 kHz. Higher capacitance is supported at lower speeds, and lower capacitance
