The 74HC165D is a 16-pin serial-in/parallel-out shift register. It is commonly used to convert parallel data inputs into a serial data output. The key pin functions are:
1. Pin 1 (Q7): Serial output of the data from the last stage.
2. Pin 2-9 (D0-D7): Parallel data inputs.
3. Pin 10 (E/CLK INH): Clock inhibit; active high to disable clock input.
4. Pin 11 (CLK): Clock input; rising edge-triggered.
5. Pin 12 (LOAD/SH): Parallel load input; active low to load parallel data.
6. Pin 13 (Q7’): Complementary serial output for cascading.
7. Pin 14 (SER): Serial data input; used for cascading.
8. Pin 15 (VCC): Positive supply voltage.
9. Pin 16 (GND): Ground.
The device reads the parallel inputs when LOAD/SH is low and shifts the data with each clock pulse when LOAD/SH is high. It's useful in applications requiring data serialization, such as interfacing multiple input signals to a microcontroller with limited I/O pins.
