The SN74HC165DR is a 16-pin device that functions as an 8-bit parallel-in/serial-out shift register. It is used to capture and convert parallel data inputs into serial output data, which is useful for expanding the input capability of microcontrollers.
Here’s a brief rundown of the pin functions:
- Pins 1-7 (A-G): Parallel data inputs. These are used to input the 8-bit data that will be shifted out serially.
- Pin 8 (GND): Ground pin.
- Pin 9 (Q7): Serial data output. This pin provides the serial output of the shift register.
- Pin 10 (Q7'): Complementary serial output, often used for cascading multiple SN74HC165DR devices.
- Pin 11 (CLK INH): Clock inhibit pin. When high, the clock is disabled and prevents any shifts in the register.
- Pin 12 (CLK): Clock pin. A rising edge on this pin shifts the data in the register.
- Pin 13 (SH/LD): Shift/load pin. When low, the parallel data is loaded into the register; when high, the device shifts data.
- Pin 14 (SER): Serial data input. Used for cascading devices.
- Pin 15 (Q7): Another serial data output pin.
- Pin 16 (VCC): Supply voltage pin.
These features make the SN74HC165DR ideal for applications where serial data communication is needed from parallel sources.
