The PCA9514D,112 is a robust I²C and SMBus buffer manufactured by NXP Semiconductors, designed to enhance the capabilities of I²C systems by providing bidirectional buffering for both data (SDA) and clock (SCL) lines. This integrated circuit allows for the extension of the I²C bus communication over longer distances and can connect multiple devices, overcoming the inherent capacitance limit of the I²C bus.

Key Features

• 5V Tolerant I/Os: Despite operating at a supply voltage range of 2.3V to 5.5V, the PCA9514D,112 is tolerant to 5V on the I/O lines, making it compatible with a wide range of devices and systems.
• Hot Swap Capability: This device can be connected to a live backplane without disrupting the communication on the bus, thanks to its hot-swapping feature.
• Low Standby Current: It consumes a very low standby current, making it suitable for power-sensitive applications.
• High Noise Immunity: The PCA9514D,112 has built-in noise filtering on the SDA and SCL lines, enhancing the reliability of communication under noisy conditions.
• Active-High Repeater Enable Input: The repeater can be enabled or disabled through a dedicated input pin, providing additional control to the user.

Applications

The PCA9514D,112 is ideal for a variety of applications where I²C bus signal integrity is critical. It is commonly used in:

• Servers and Networking Equipment
• Telecommunications
• Industrial Control Systems
• Consumer Electronics
