The PCA9509GM,125 from NXP Semiconductors is a versatile 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 (Port B). Port A supports a voltage range from 1.35 V to VCC(B) - 1.0 V and does not require external pull-up resistors due to its internal current source. Port B operates from 3.0 V to 5.5 V and is overvoltage tolerant. The repeater is lock-up free and supports arbitration and clock stretching.
Key electrical specifications include a maximum data rate of 400kHz, 2 channels, and an operating voltage range of 3V to 5.5V for Port B. The operating temperature range is -40°C to 85°C. The PCA9509GM,125 is available in an 8-XQFNU (1.6x1.6) package and is designed for surface mount applications.
This repeater is suitable for applications requiring voltage level translation between different I2C or SMBus domains, ensuring reliable communication in mixed-voltage systems.
