The 74HC165 is a versatile Parallel In Serial Out (PISO) shift register manufactured by STMicroelectronics. This component is designed to significantly increase the number of input pins available for microcontrollers, allowing for the connection of multiple sensors or digital inputs through a single serial output.
With 8 parallel input pins (A-H), a serial data output (SER), a clock input (CLK), and a clock enable input (CLK INH), the 74HC165 facilitates efficient data acquisition. It can be cascaded with other 74HC165 devices to further expand the input capacity, enabling control of up to 24 digital sensors with a single Arduino pin when three shift registers are connected in parallel.
This shift register is compatible with various microcontrollers, including Arduino, PIC, and Atmel devices. Its primary application is in systems requiring a large number of digital inputs to be read serially, such as in automation, data logging, and embedded systems where pin count is a constraint.
