PCA9517D,118 Description

Short technical summary and product information.

The PCA9517D,118 from NXP Semiconductors is a versatile 2-channel buffer and re-driver designed for I2C and SMBus applications. It facilitates level shifting between low-voltage (0.9 V to 5.5 V) and higher-voltage (2.7 V to 5.5 V) buses, enabling seamless communication in mixed-voltage systems.

 

This device extends the I2C-bus by providing bidirectional buffering for both the data (SDA) and clock (SCL) lines, supporting up to 400 pF on either side. The PCA9517D,118 allows system designers to isolate bus segments for voltage and capacitance management. Its SDA and SCL pins are over-voltage tolerant and become high-impedance when the device is unpowered.

 

The PCA9517D,118 is compatible with I2C and SMBus protocols and operates at a maximum data rate of 400kHz. It features an active-high enable input for system control. The device is housed in a compact 8-SOIC package and is designed for surface mount applications, operating within a temperature range of -40°C to 85°C.
