Overview

The 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

Application Ideas:

  • Voltage requirements: 2-6 VDC
  • Current requirements: 80 uA max
  • Communication: Parallel in/Serial out (SPI type / 3-wire output)
  • Package: DIP-16 (0.300")
  • Operating temp range: -40 to +158 °F (-40 to +85 °C)
