The 74HC165 is a high-speed CMOS 8-bit parallel-in serial-out shift register IC, perfect for expanding the number of input lines available to a microcontroller or digital system. Supplied in a standard 16-pin DIL through-hole package, it's easy to solder onto prototyping boards, stripboards, and custom PCBs.
By loading parallel input data and shifting it out serially, the 74HC165 allows multiple digital inputs to be read using only a few pins—ideal for applications such as button matrices, keypads, and sensor arrays. It's fully compatible with popular development platforms like Arduino, Raspberry Pi, and PIC microcontrollers.
