The Parallax 74HC165 Parallel to Serial Shift Register allows you to add 8 input pins to your microcontroller using an SPI type (3-pin) interface.
Additional shift registers may be daisy chained to add inputs in multiples of 8 with no additional I/O pins required on the microcontroller.
Shift registers like this are often used in video game controllers to read all the pad/button information and get it to the console serially.
Key Features:
- Easy to control from a BASIC Stamp Module using SHIFTIN command
- Typical propagation delay: 20 ns (clock to Q)
- Fanout of 10 LS-TTL loads
