The PCA9511ADP,118 is an IC component designed by NXP Semiconductors. It is a level-translating I2C-bus repeater that expands the capabilities of the I2C-bus and allows longer bus lengths and more nodes.
Key features of the PCA9511ADP,118 include:
1. Two-channel bidirectional buffer: The IC has two bidirectional buffers that enable independent and bi-directional voltage level translation between any two I2C buses.
2. Auto-direction sensing: The PCA9511ADP,118 has auto-direction sensing capability, which eliminates the need for any control mechanism to determine the direction of data flow.
3. Voltage level shifting: It supports voltage level shifting between 3.3V and 5V buses, allowing devices operating at different voltage levels (VCC2) to communicate seamlessly.
4. Slew rate control: The IC provides slew rate control on the SDA and SCL lines to reduce noise and signal distortion during high-speed transmission.
5. Noise filtering: The PCA9511ADP,118 includes noise filtering on the SDA and SCL lines, aiding in the rejection of noise and improving signal integrity.
6. Bus fault detection: It incorporates a bus fault detection circuit that monitors the I2C bus lines for bus faults, such as stuck bus conditions or excessive bus capacitance
