PCA9507DP,118

The PCA9507DP,118 is a 2-wire serial Bus Extender providing 3.3 to 5 V level shift that allows up to 18meters bus extension for reliable DDC, I?C-bus or SMBus applications. While retaining all the operating modes and features of the I?C-bus system during the level shifts, it also permits extension of the I?C-bus by providing bi-directional buffering for both the data (SDA) and the clock (SCL) line as well as the rise time accelerator on port-A enabling the bus to drive a load up to 1400pF or distance of 18m on port-A and 400pF on port-B. Using this enables the system designer to isolate bus capacitance to meet HDMI DDC version 1.3 distance specification. The SDA and SCL pins are overvoltage tolerant and are high-impedance when the repeater is unpowered.
