• Six bi-directional channels
• Easy to use and space saving
• Ideal for embedded systems, automotive applications, robotics, IoT, etc.

Application

The PCA9541BS/01,118 is ideal for applications which require selectors or multiplexers. It can be used in digital cameras, digital video cameras, cell phones, tablet PCs, and other portable electronic devices. It can also be used in communication systems, automotive applications, and in light control systems. In addition, it can be used in digital displays, embedded systems, and other systems which require an easy-to-use and space-saving selector circuit.

Working Principle

The PCA9541BS/01,118 is a bi-directional, digital, I2C-bus master selector circuit that works with a pair of data lines (SDA and SCL). The circuit includes an on-chip serial converter which converts the incoming data, including the address and command signals, into proper digital signals which are then output on the I/O port. The on-chip serial converter also provides the required timing and interrupt signals to the processor and the I/O port. The user can then select any of the six selector pins with an on-chip selector switch.

The PCA9541BS/01,118 selector circuit can also be used in combination with other logic ICs to provide more sophisticated functions. For example, it can be used in conjunction with address decoders, multiplexers, and CD/IO devices. The PCA9541BS/01,118 also features a power-down mode, which allows the user to reduce the power consumption and minimize the device\'s footprint when not in use.
