The PCA9536TK,118 is an interface- I/O Expanders developed by NXP Semiconductors, a leading producer of digital logic devices. This device provides a low-cost, simple solution for expanding single-chip microcontroller I/O capabilities by adding machine-drilling, optocouplers, LED displays, keyboards and rotary encoders. The device works by providing a series of independent I/O lines which can be connected to a wide variety of input and output devices. It also includes a number of control functions such as direction control, pulse-width modulation (PWM), frequency generator, analog-to-digital conversion, and open-collector outputs.

PCA9536TK,118 consists of 6-bit wide I/O port which can be used as either inputs or outputs. It also has two additional control lines that provide advanced interrupt capabilities and supply power for certain devices. The device requires a +5V supply voltage, but can also operate from single +3V power supply. The I/O lines can be configured as either input or output with the provided control signals. Direction control allows the user to choose whether a particular port line is set as an input or an output. So, the device can be used for interfacing applications with either input or output device.

The PCA9536TK,118 application field is diverse and includes medical applications, robotics, car audio, industrial cost automation and home automation. It is suited for applications where multiple inputs and outputs of low-voltage devices need to be connected in an efficient and controlled way. The device is used as a general-purpose I/O expansion chip and can be used to interface with various types of sensors and actuators in various applications. It is designed to detect input signals from contact closure switches, proximity sensors and thermal transducers.

The device’s working principle is quite simple. It works by connecting to an input device (such as contact closure switch, proximity sensor or thermal transducer) and outputting the corresponding information on the connected output device (such as LED display, voice synthesizer or printer). The device uses digital-to-analog and analog-to-digital conversion to send or receive data on its associated I/O lines. This enables the device to join a microcontroller system, providing it with more I/O ports and a greater variety of output devices.
