PCA9515A Datasheet | NXP Semiconductors

I2C-bus repeater Rev. 5 - 23 March 2012 Product data sheet 1. General description The PCA9515A is a CMOS integrated circuit intended for application in I2C-bus and SMBus systems. While retaining all the operating modes and Features of the I2C-bus system, it permits extension of the I2C-bus by buffering both the data (SDA) and the clock (SCL) lines, thus enabling two buses of 400 pF. The I2C-bus capacitance limit of 400 pF restricts the number of devices and bus length. Using the PCA9515A enables the system designer to isolate two halves of a bus, thus more devices or longer length can be acmodated. It can also be used to run two buses, one at 5 V and the other at 3.3 V or a...
