About this product
The 74HC165 is an 8-bit shift register that loads data from parallel inputs D0 to D7 asynchronously when PL is LOW, then shifts it out serially on each clock pulse while PL is HIGH. It provides complementary serial outputs Q7 and Q7-bar, and devices can be cascaded by connecting Q7 to the DS input of the next stage. It is a practical way to read many digital inputs using only a few microcontroller pins.

How do I read 8 switches with the 74HC165?
Connect each switch to a parallel input D0 to D7 with a pull-up or pull-down resistor. Pulse PL LOW to load the switch states, then set PL HIGH and clock the bits out one at a time from Q7.
Can I chain several 74HC165 devices together?
Yes. Connect Q7 of one device to the DS input of the next, and share the clock and PL lines across all devices. The data then appears as one longer serial stream.
