The PCA9509DP,118 from NXP Semiconductors is a level-translating I2C-bus/SMBus repeater. It enables low-voltage processors to interface with standard I2C-bus or SMBus I/O, extending the I2C-bus capability. This device provides bidirectional buffering for both data (SDA) and clock (SCL) lines, allowing for a maximum capacitance of 400 pF on the higher voltage side.
Key electrical specifications include an operating voltage range of 3V to 5.5V and a maximum data rate of 400kHz. It features 2 channels and supports I2C applications. The repeater is designed for lock-up-free operation and accommodates standard-mode and fast-mode I2C-bus devices, including multiple masters. It also supports arbitration and clock stretching across the repeater.
Packaged in an 8-TSSOP, the PCA9509DP,118 is designed for surface mount applications. Its open-drain inputs/outputs and powered-off high-impedance I2C-bus pins contribute to its robust design. The device requires no external pull-up resistors on the lower voltage port A, simplifying circuit design.
