Quality Control: Learn More
The NXP Semiconductors PCA9661B is a CMOS I2C bus controller featuring an 8-bit address bus width and compatibility with the I2C standard. This device supports a maximum clock frequency of 12 MHz and a maximum data transfer rate of 0.125 Mbps. It adheres to the IEEE 1149.1 drive interface standard. The PCA9661B is housed in a 48-terminal, square, low-profile fine-pitch flatpack (LFQFP) with a terminal pitch of 0.500 mm. Operating within a temperature range of -40°C to +85°C, it requires a supply voltage between 3.0V and 3.6V, with a nominal value of 3.3V. Its plastic/epoxy package construction and gull wing terminal form indicate suitability for surface mounting applications. This component finds utility in industrial automation, consumer electronics, and automotive systems.
