Product Introduction

Overview

The PCA9515AD,118 is a CMOS integrated circuit designed by NXP USA Inc. for use in I2C-bus and SMBus systems. This component is specifically intended to extend the capabilities of I2C-bus systems by buffering both the data (SDA) and clock (SCL) lines. This buffering enables the system to accommodate more devices or longer bus lengths, overcoming the 400 pF capacitance limit of standard I2C-bus systems. The PCA9515AD,118 allows for the isolation of two halves of a bus, enabling the operation of two buses at different voltages (e.g., 5 V and 3.3 V) or frequencies (e.g., 400 kHz and 100 kHz).

Applications

The PCA9515AD,118 is ideal for applications where the I2C-bus capacitance limit needs to be extended. It can be used in systems that require the isolation of two halves of a bus, allowing for more devices or longer bus lengths. This component is particularly useful in scenarios where different voltage levels or frequencies need to be supported on the same bus, such as in mixed-voltage systems or systems requiring both 400 kHz and 100 kHz operation.
