The PCA9517D,118 is an integrated circuit component developed by NXP Semiconductors. It is a level-translating I2C-bus repeater that provides bidirectional voltage level translation between low voltage and higher voltage I2C buses. This component allows different voltage levels to coexist and communicate within an I2C system.
Here are some key features of the PCA9517D,118:
1. Bidirectional voltage translation: The PCA9517D,118 can translate signals between two different voltage levels, allowing devices operating at different voltages to communicate seamlessly in an I2C bus.
2. Wide voltage range support: This component supports a voltage range from 1.0V to 5.5V for both the low voltage and high voltage sides, making it compatible with a wide range of devices and systems.
3. Automatic direction sensing: The PCA9517D,118 automatically senses the direction of data flow and adjusts the direction of voltage translation accordingly, simplifying the design and implementation of multi-voltage level I2C systems.
4. High-speed operation: With a maximum operating frequency of 400 kHz, the PCA9517D,118 can support high-speed I2C communication, enabling quick and efficient data transfer.
5. Low power consumption: This component features a low power mode, where it consumes minimal power when not actively translating signals. This helps to conserve energy and prolong the battery life of portable devices
