The PCA9518APW,518 is an IC component that serves as a level shifting and bus buffering device. It is designed to enable I2C and SMBus systems to interface with different voltage levels, ensuring reliable communication between devices operating at different voltage levels. Here are some key features of the PCA9518APW,518:
1. Level Shifting: The PCA9518APW,518 can shift voltage levels between two buses, allowing devices operating at different voltages to communicate effectively. It supports level shifting between low voltage devices (1.0 V to 3.6 V) and high voltage devices (1.8 V to 5.5 V).
2. Bidirectional Voltage Translation: This IC component provides bidirectional voltage translation for I2C and SMBus applications, allowing data to be transmitted in both directions between devices.
3. Active-High Detect Outputs: The PCA9518APW,518 features active-high detect outputs, allowing the user to monitor the status of the I2C bus voltage levels. These detect outputs can be used for system-level fault detection and troubleshooting.
4. Independent Power Supply Inputs: It has separate power supply inputs for low and high voltage sides, offering flexibility in powering the device. This feature helps in isolating power supply noise and optimizing performance.
5. Bus Buffering: The PCA9518APW,518 acts as a bus buffer, providing high current drive capability on both the low voltage and high voltage sides
