74HC165 Parallel to Serial Shift Register

Product Description Quantity limited to stock on hand. 74HC165 Parallel to Serial Shift Register 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 74HC165 Parallel to Serial Shift Register Details: 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)
