PCA8550DR is part of Philips Semiconductor\'s logic-signal switches, multiplexers, decoders product group. It is a CMOS monolithic device with 8 bit I/O ports. It is suitable for a variety of digital system applications that offer data channeling, port decoding, and power saving for secured data operations.The PCA8550DR has a combined input/output structure which simplifies the data exchanges and multiplexing operations between its two I/O ports. It can be used to source and sink a variety of logic signals at the same time, reducing the number of pins needed for connecting the signals to external processors or controllers.The PCA8550DR is designed for wide power supply voltage range that starts from 3.3V and goes up to 12V, making it suitable for a wide range of applications. In addition, the PCA8550DR also provides a maximum power dissipation of 1.6W.The PCA8550DR has an ON/OFF pin that enables the user to enable and disable the device at any time. This feature helps in reducing power dissipation, particularly when the device is not active and no data exchanges are taking place.The PCA8550DR has four independent buffers with active high outputs. When the pin is in the ON/OFF state, respective buffer will follow the input signal to the respective port; otherwise, the buffers are disabled and the input signal ignored. This behavior facilitates and customized I/O combinations.The PCA8550DR is designed to work with a wide range of logic levels from TTL to CMOS, making it suitable for various operating environments. The device is also compliant with EMI/RFI immunity standards, making it suitable for protected data operations in noisier environments.The PCA8550DR provides a very fast signal speed of 10nS along with low power dissipation of 1.6W, making it an ideal choice for high speed applications. It also has a wide range of noise immunity characteristics, making it suitable for secure operations in various operating environments.
