Additional Details:
The TC74HC165AP(F) is typically packaged in a 16-pin DIP (Dual In-line Package). It requires a clock signal to shift the data and a load enable signal to load the parallel data. The data is shifted out serially on the Q7 output. Refer to the Toshiba Semiconductor and Storage datasheet for specific details regarding timing characteristics, voltage ratings, and pin configurations. Input protection circuitry is included to protect against electrostatic discharge (ESD).
